Abstract :
This paper discusses the design and construction of an 18 kW matrix converter induction motor drive. The converter uses gate drive level intelligence in the form of an FPGA to control device current commutation. Current direction is determined using device voltages and therefore the problems with other methods of current commutation at low currents are overcome. Strategies for circuit protection due to loss of the input voltage supply are also discussed. Practical results are presented
