A realization of three phase to three phase matrix electric power converter (33MC) with practicality is depicted, which is characteristic of modular configuration, simple and safe semi-natural semi-forced two-step commutation strategy, general over-current protection circuit, flexible generalized switching functions, combined bilateral power switches, and so on. A new approach to manufacturing-oriented 33MC comes forth, which is composed of 3 modular three phase to single phase non-square matrix electric power converters (31MC).
