In recent years, significance of semiconductor module for photovoltaic power conversion systems is increasing. Especially higher output power with existing housing size of power module is important to realize further downsizing or rating upgrade for its systems. For realizing higher
At least two power reactors are needed for solar inverters: one in the boost converter (step-up chopper) and one at the ouput of the inverter for EMC filtering. Besides the IGBTs, the losses in the reactors are a major determining factor of the overall efficiency of the inverter
