Abstract

This paper presents parallel operation of two 3-phase PWM converters whose Power and control schemes can be directly applied to a large capacity system. This paper describes power circuit, dc voltage regulation, input power factor correction and balancing load control of two converters. Switching device Is IGBT and CPU of control is 32-bit floating point DSP for real time instantaneous control. Simulations and experimental results for 20kw model conform the validity of proposed schemes.
