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).
