Abstract
A hybrid DC/AC inverter for converting DC power to AC power feed to a grid voltage system has an input circuit, a half/full bridge switchable circuit and an output circuit. The input circuit has two input terminals for connecting to a DC source and outputs the DC power. The half/full bridge switchable circuit can be operated in a buck mode based on amplitudes of the DC power and the grid voltage. The output circuit is for connecting to the grid voltage system. According to comparison results between of the DC power and the grid voltage, the half/full bridge switchable circuit is selectively operated in the buck mode to reduce switching loss and power consumption.
