The supply receive from 220 /120/110 Volt AC , then lowered by the transformer . Then receives +20 Volts DC from rectifier / filter section. This applied to pin 11 and 12 of the IC uA723/LM723 , as well as to the collector of the 2N3055 series pass transistor. The output through R1 and R2, providing about 7 V with respect to ground at pin 4. The reference terminal at pin 6 is tied directly to pin

2 Watt Switching Power Supply
2 Watt Switching Power Supply SchematicIn this small 2 Watt Switching Power Supply, a Schmitt activate oscillator is acclimated to drive a switching transistor that food accepted to a baby inductor. Energy is stored in the inductor while the transistor is on, and appear into the amount ambit back the transistor switches off. The achievement voltage is abased on the amount attrition and is bound

200W ATX PC Power Supply uses chip TL494
200W ATX PC Power Supply uses chip TL494This ability accumulation circuit uses chip TL494. Similar ambit is acclimated in the best ability food with achievement ability about 200W.Device use push-pull transistor ambit with adjustment of achievement voltage. Line voltage goes through ascribe clarify circuit (C1, R1, T1, C4, T5) to the arch rectifier. When voltage is switched from 230V to 115V,

Dual Power Supply using LM 320 and LM 340
Number of signs needed and bipolar integrated circuits (double V ± o) supplies. This can be done easily with two three-terminal regulators, as illustrated in Fig. Faced with the CA phase is provided by the transformer secondary and a center tap to ground. The only full-wave bridge converts these into positive and negative voltages (with respect to the center tap to ground). Filtration (to ground
