15 Ampere Adjustable Power Supply

15 Ampere Adjustable Power Supply
This adjustable power supply circuit provides an output voltage source which can be adjusted between 1.5 and 15 volts and give 15 amps current. As is shown in the wiring diagram the 15 A adjustable power supply provides similar amount of current through the parallel work of four power transistors, which must be mounted on a good heatsink. The voltage adjustment is performed in integrated LM317, which also must be dissipated mechanically. (more…)

Power Supply for 1500 Watt Audio Power Amplifier

Power Supply for 1500 Watt Audio Power Amplifier
This Power supply circuit is paired with High Power audio amplifier 1500 watts. Power supply required for the amplifier requires a serious approach to the design. First you need a step-down transformer capacity of at least 2kW.  Supply filter capacitors should be designed to withstand up to 150V and 10A pulsed current. Capacitors do not meet these requirements may simply explode if the amplifier at full power. (more…)
