A power supply that has to provide 5 Amperes will need a 10,000uF capacitor. Obviously the larger the capacitor the better. Because the power supply is only charging the capacitors at the peak of each cycle for only 1/10 of the time means the overall efficiency of a 'Capacitor Input' power supply is approx 70%.

Answer (1 of 10): Fundamentally, yes, the functional blocks of a switching power supply and a switching audio amplifier are the same. A switching audio amplifier however, has to behave approximating a voltage source out to 20 kHz, while a DC power supply only has to regulate a DC values. You coul...
