Amplifier power supply using High Current Transformer

Friends ever meet a problem power supply Circuit give current not enough. I has way this out give friends try apply. Follow this circuit High Current transformer parallel circuit make you have Current tall go up very. The transformer that have many the coil , we can bring to do high Current power supply circuit well. By if the all coil has Voltage be equal. It is can bring parallel can follow this circuit is coil lead that has Voltage 24V and have Current about 1A come to parallel prevent all 2 the group have current altogether each 2A groups by have voltage at 24V be the same. This circuit then can become Dual power supply at 34V positive and -34V Negative and Ground. This circuit uses to are amplifier power supply get good. Suppose will give the electric power about 50watt. For the diode use 3A 100V sizes and use. The Stancor for filter noise signal the all well. This circuit may help to give testimony have the idea in applying work other , get please sir.

DC power supply +24V and -24V for Power Amplifier 30W

This is circuit DC power supply +24V and -24V for Power Amplifier OCL Hifi 30W.
It is Current output 2A Max, Easy circuit and build easy too. See in image.

Power Supply +24V / -24V 3A for amplifier hifi

The main power supply is relatively conventional – the mains supply is presented to the torroidal transformer via a fuse, a thermal cut-out and the power switch. A device that looks like a VDR is mounted on the power switch…

The secondary windings produce ±24V nominally using discrete diodes and 2 reservoir capacitors. The second pair of capacitors is fed via 0.47Î© resistors which reduce ripple by a good amount – I measured 0.8V pk-pk across C3 and 0.25V pk-pk across C4. A cheaper version of the choke PSU’s that MF use these days…
The smoothing capacitors are rated at 25V – rather close to the limit in my opinion!
