Abstract
This paper proposes an improved ZVS-ZCS ARCPI (auxiliary resonant-commutated pole inverter) to solve the problems, such as extra losses from auxiliary circuit, variable commutation duration, and poor reliability, which are common in existing ARCPIs. In this enhanced ARCPI, the introduction of commutation forcing voltage greater than half value of DC link voltage, fixed commutation duration, and protection for auxiliary switches, enhances the performance, and also extends its application. Based on the analysis, simulation, and experimentation, this new ARCPI is proved reasonable for use in high reliability application such as DFACTS.
