Abstract

In this paper, high efficiency control method for interleaved flyback inverter with synchronous rectifier based on photovoltaic AC modules is proposed. In this control method, using synchronous rectifier, a main switch is operated with the soft switching in the region that ACC(Active Clamp Circuit) isn´t operated for reducing loss of the ACC. Therefore, a switching loss of the main switch can be reduced. A theoretical analysis and the design principle of the proposed method are provided and its validity is confirmed through simulation results.
