A Versatile Inverter for Educational Purposes

This paper presents an experimental chopper-inverter system which we use for most of our lab work in power electronics. The system is based on an IGBT three-phase voltage inverter and a FPGA control board. According to the configuration chosen by the user, this set can constitute a converter in a predefined list ranging from the simple non reversible buck converter up to the three-phase PWM power inverter with constant V/f modulation. A detailed description of the experimental system is given. In addition some practical examples of use in power engineering labs are illustrated experimentally
