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. .

Grid-tie inverters convert DC electrical power into AC power suitable for injecting into the electric utility company grid. The grid tie inverter (GTI) must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant. A high-quality modern grid-tie inverter has a fixed unity, which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The inverter has an internal com.
