Skema Rangkaian Regulator Rectifier atau Kiprok untuk Sepeda Motor

Para penggemar sepeda motor tentu diantara anda ada yang dibuat pusing dengan regulator rectifier sepeda motor atau yang suka disebut kiprok yang sering mengalami kerusakan terutama lampunya yang sering putus akibat kerusakan kiprok dan tidak stabilnya tegangan yang dihasilkan dari rangkaian regulatornya. Postingan ini juga sekaligus sebagai balasan untuk ananda Wahyu Handono Riyadh yang menginginkan skema rangkaian regulator rectifier alias kiprok. Beliau mempunyai pengalaman pembelian regulator rectifier berkali kali tapi rusak terus meskipun katanya sudah membeli yang asli. Rangkaian regulator rectifier biasanya hanya terdiri dari dioda penyearah yang berfungsi untuk mengubah arus ac menjadi dc dan sebagai pengisi accu dan untuk menstabilkannya biasanya  memakai dioda zener sebagai suplai tegangan ke lampu, klakson dan lainnya. 
Oke langsung aja yah ke TKP seperti apa rangkaian yang akan dikemukakan. Rangkaian Kiprok ini saya ambil dari blognya bang ONIX .  Beliau adalah penggemar sepeda motor Vespa dan suka berkreasi.


Rangkaian ini cukup sederhana namun hasilnya saya kira tidak akan mengecewakan. Rangkaian kiprok ini menggunakan IC LM2576-15V sebagai regulator. Outputnya bisa menghasilkan 15Volt 3Ampere jadi sangat cocok untuk pengisian Accu, input IC ini bisa mencapai 60V jadi sangat aman apabila motor di gas sekencang apapun. Sebagai sumber tegangan diambil dari spull lampu besar seperti pada diagram dibawah ini:
Selamat mencoba dan semoga berhasil!

Pengatur Suhu Ruangan Elektronik

Skema Rangkaian Pengatur Suhu Elektronik ini dirancang menggunakan L121 sirkuit terpadu diproduksi oleh SGS THOMSON. Sirkuit ini dapat digunakan untuk mengatur suhu di dalam kendaraan atau pada rangkaian Power Suplay. Rangkaian ini menggunakan tegangan suplay 12 Volt. Rangkaian elektronik ini memungkinkan suhu yang diinginkan di dalam ruangan yang bervariasi antara dua batas. Suhu ruangan dideteksi oleh NTC termistor (koefisien temperatur negatif) dengan nilai nominal 47 K pada 25 ° C.

Penurunan tegangan pada termistor yang digunakan untuk mengatur tingkat ke salah satu input dari L121 penguat operasional. Ambang ini menentukan output penguat operasional sirkuit beralih urutan integrasi. Potensiometer P2 menyesuaikan input kedua dari penguat operasional yang sama dan digunakan untuk meresepkan suhu di mana sirkuit masuk ke dalam operasi.

Bila suhu di dalam ruang meningkat, resistansi thermistor menurun, dan akan menyebabkan tegangan di pin 3 menurun. Setelah beberapa waktu, himpunan P2 tercapai, menyebabkan rangkaian logika tipping dari IC1. Ini akan menentukan input ke T1 konduksi transistor, yang akan menghidupkan kipas angin sehingga menghasilkan udara dingin. Setelah suhu turun pada batas nilai yang ditentukan oleh P1, rangkaian kontrol akan mematikan kipas angin kembali.

Soft Start For Switching Power Supply

extremecircuits.net
Switching power supply whose output voltage is appreciably lower than its input voltage has an interesting property: the current drawn by it is smaller than its output current. However, the input power (UI) is, of course, greater than the output power. There is another aspect that needs to be watched: when the input voltage at switch-on is too low, the regulator will tend to draw the full current. When the supply cannot cope with this, it fails or the fuse blows. It is, therefore, advisable to disable the regulator at switch-on (via the on/off input). until the relevant capacitor has been charged. When the regulator then starts to draw current, the charging current has already dropped to a level which does not overload the voltage source.

Circuit diagram:
Soft Start Circuit For Switching Power Supply

The circuit in the diagram provides an output voltage of 5 V and is supplied by a 24 V source. The regulator need not be disabled until the capacitor is fully charged: when the potential across the capacitor has reached a level of half or more of the input voltage, all is well. This is why the zener diode in the diagram is rated at 15 V. Many regulators produced by National Semiconductor have an integral on/off switch, and this is used in the present circuit. The input is intended for TTL signals, and usually consists of a transistor whose base is accessible externally. This means that a higher switching voltage may be applied via a series resistor: the value of this in the present circuit is 22 kΩ. When the voltage across the capacitor reaches a level of about 17 V, transistor T1 comes on, whereupon the regulator is enabled.

Power Supplay 12 Volt Non Trafo


 This circuit will supply up to about 20ma at 12 volts. It uses capacitive reactance instead of resistance; and it doesn’t generate very much heat.The circuit draws about 30ma AC. Always use a fuse and/or a fusible resistor to be on the safe side. The values given are only a guide. There should be more than enough power available for timers, light operated switches, temperature controllers etc,

UPS POWER SUPPLY CIRCUIT

This circuit can be adapted for other regulated and unregulated voltages by using different regulators and batteries. For a 15 Volt regulated supply use two 12 Volt batteries in series and a 7815 regulator. There is a lot of flexibility in this circuit.

Stabilised Power Supply with Current Limiting

A simple bench PSU capable of :-
Approx. 5v to 15v output at 1A
Current limited from about 500mA to 1A (adjustable)

Circuit Operation:
An error amplifier is formed from Tr1 and Tr2, wired as a differential amplifier (often called a long-tailed pair -- look at those collector leads). One input of this diff. amp is taken from the zener diode which provides a stable 4.7 volts, the other diff. amp input is a fraction of the output. Any difference between the two will cause the current through R3 to alter and so will alter the voltage across it and hence to the base of Tr3.

Alarm Kegagalan Power Suplay (Power Supply Failure Alarm)

Power supply failure indicator circuits
Most of the power supply failure indicator circuits need a separate power supply for themselves. But the alarm circuit presented here needs no additional supply source. It employs an electrolytic capacitor to store adequate charge, to feed power to the alarm circuit which sounds an alarm for a reasonable duration when the supply fails.

Circuit of adapter 12 volt
Gbr. Skema rangkaian adaptor 12 volt, 5 ampere

Now it should not have to wrestle again seek op-amp, transistor and other components to realize a massive circuit of regulators, because the circuit of this kind have been packed into a fixed voltage regulator IC. Currently, many components known as the 78XX series fixed positive voltage regulator and the 79XX series is a voltage regulator to remain negative.

Power supplay (Adapter) 12 Volt

12 volt dual voltage of adapter


Variable Adapter (3 , 4 ,5 ,9 ,12 ,16 ,20 to max 37 volt)


The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. Also, the LM117 is packaged in standard transistor packages which are easily mounted and handled.
Variable adaptorIn addition to higher performance than fixed regulators, the LM117 series offers full overload protection available only in IC's. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected.
Normally, no capacitors are needed unless the device is situated more than 6

Regulator is a series of regulations or the voltage output from power so that a portion darinaik effects or voltage drop in net does not affect the voltage ration power to be so stable.

Regular circuit of regulators have been good if the ripple voltage is small, but there is a problem of stability. If the voltage PLN rise /down, then the output voltage is also will be rise /donw. regular circuit of regulators, if the current of the larger, the dc voltage output is also down. For some applications this voltage change will very disrupt.

Rangkaian +5V Switching regulator

Switching regulatorRangkaian +5V Switching regulator used LM2575-5.0. You can make the stable voltage by using the 3 terminal regulator like LM317. However, because the output electric current and the inputted electric current are the same approximately, the difference between the input electric power (The input voltage x The input electric current) and the output power (The output voltage x The output current) is consumed as the
