Abstract:
An inverter of a power supply apparatus includes a smoothing circuit. The smoothing circuit includes a circuit body having a positive-side output terminal and a negative-side output terminal, and a plurality of capacitors mounted on the circuit body and connected in parallel between the positive-side output terminal and the negative-side output terminal. A difference between the maximum value and the minimum value among positive-negative electrical path lengths lnPNi = lnPi + lnNi (i = 1, 2, and 3) for the respective capacitors is equal to or smaller than 30% of the minimum value.
