Abstract:
A method for operating a matrix converter in which m phases of a source delivering alternating voltage are alternatingly connected with n phases of a load via a multiple number of controllable bidirectional switches arranged in an (mÃ—n) matrix, comprising:switching over from a first phase of the source to a second phase of the source only when the condition IkÂ·(Vkâˆ’Vl)Â·Kijkl<0 â€ƒis met, where Ik and Vk are the current and the voltage of the first phase, Vl is the voltage of the second phase and in each instance Kijkl is a characteristic constant for the mutual inductance between the phases of the source and the inductance of the load.
