Description
Summary:In this paper the design and testing of new concepts in matrix converter construction and control are presented. The matrix converter has a more complex commutation behaviour and over-voltage protection in emergency switch-off compared to the voltage-link converter. New investigations have overcome this problems. The new revolutionary concepts in protection, commutation, switch design and modulation strategy are simple and cheap. A further milestone towards an easy design for a matrix converter has been achieved. The practical operation of the new concepts are verified on a 5.5 kW matrix converter drive system with an induction motor.
