Amplifier Power Supply Schematic Diagram. 300w subwoofer power amplifier schematics wiring diagram circuits schema electronic projects. 12v 15v 15v 35v 35v and dual up to 70v max using zener diode as base for steady voltage output.

Generally pcb designs are made with protection circuits. Creating a low impedance connection between the positive and negative power supply rails. 12v 15v 15v 35v 35v and dual up to 70v max using zener diode as base for steady voltage output.

120w power amplifier power supply.

It is somewhat similar to the above explained dc to dc converter but instead of direct dc power supply here ac input is used. So the combination of the rectifier filter shown in the block diagram is used to convert the ac into dc switching is done by using a power mosfet amplifier with which very high gain can be obtained. 50w amplifier schematics wiring diagram circuits schema electronic projects.
