SMPS switch mode power supply circuit power amplifier used in the output symmetrical + – 50v 4N35 opto-coupler connected to the 10k potentiometer with a voltage adjustment can be done, of course, extremely high or low should not be set higher voltages for the output filter capacitor voltage must be increased and the transformer’s secondary winding number should be increased to + -75v 2×28 tour was called.
Power Amplifier SMPS Circuit
SG3525 as integrated control (PWM control pulse width modulator) used IR2110 SG3525 outputs (high speed power MOSFET IGBT drivers) IRFP460 MOSFET driver plowed strengthened with power transformer ETD49 used to. PCBs have file prepared by the PCB Wizard
