摘要： An H-bridge micro inverter grid-connected device is invented to solve the problem that failure of any photovoltaic panel on the existing solar photovoltaic system cascade can cause efficiency reduction of the whole photovoltaic panel module. The H-bridge micro inverter grid-connected device comprises a single-chip microcomputer controller, a CPLD controller, a MOSFET full-bridge circuit, a high-frequency transformer, a half-bridge rectifying circuit, an SCR full-bridge circuit and a filter circuit, wherein the MOSFET full-bridge circuit is in the full-bridge type, the high-frequency transformer is a single-phase transformer with a central tap, and the SCR full-bridge circuit is applied. The integral structure above is characterized by the decreasing number of components, the reduction of power switches, and the simplification of the control circuits and driving circuits, so as to decrease the number of full-control switch components, improve the system reliability and reduce the system costs.
