Abstract
An automatic balance adjusting device for an AC power supply is provided between the AC current output terminals of an AC power supply and its feedback control circuit. The device uses a two-level filter to extract the DC component of an AC output signal. The DC error is accumulated and amplified by an integrator and converted from a voltage form to a current form. Through a photo coupler designed for the separation purpose, the error signal is sent back to the feedback control circuit to perform compensation. Thus, the device can achieve the purpose of automatically balancing the positive and negative half-cycle waveform of the output signal.
