The unidirectional high-frequency-link DC-AC converters are becoming popular for applications like grid integration of photovoltaic systems and fuel cells [1], [2]. The high frequency galvanic isolation provides high power density, light weight converter solution. The topology is targeted for grid integration of util-ity scale renewable and alternative energy sources like solar, fuel cell, and wind, where the power flow is. . Abstract: The steady-state principle characteristics of the high-frequency pulse AC link inverter and the uni polar phase-shift control strategy are deeply analyzed and studied. The average model of the inverter is established by using the state space average method, and the design criteria of key. .
