Abstract
A power supply apparatus including: a boost converter configured to generate a power supply voltage to drive to a load circuit from a voltage received from a voltage generation unit; an oscillator configured to receive the minute voltage, and to generate an alternating current signal; and a signal conversion circuit which further includes a half-wave generation circuit configured to receive the alternating current signal, and to generate a half-wave signal of a high potential side or a low potential side, and at least one inverter configured to receive the generated half-wave signal, and to generate a pulse signal; wherein the boost converter is driven by the pulse signal output from the signal conversion circuit in order to generate the power supply voltage.
