專利摘要

A method of compensating output voltage distortion of a half-bridge inverter and a device based on the method discloses that the method includes the steps of measuring the voltage of the capacitor of the half-bridge inverter and then detecting the output voltage of the same; comparing the capacitor voltage and the output voltage to identify how much degree the distortion is resulted from the capacitor voltage unbalance, wherein if the degree of the distortion matches a predetermined condition, proceed to the next step; and charging the capacitor through a compensating circuit to compensate the capacitor for the insufficient electric energy to enable the capacitor to provide the load with the sufficient electric energy. Thus, the drawback that the waveform of the output voltage can be improved to enable the device and the method to have advantages of simple circuit, easy control, reduced capacitance, and being applicable to any output frequency.
