ABSTRACT:
A matrix converter utilizes a bidirectional lateral insulated gate bipolar transistor (IGBT) including two gate electrodes. The IGBT can conduct in two directions. The matrix converter preferably is a three phase matrix converter including nine bidirectional IGBT switches. The IGBT switches are controlled by a control circuit which includes eighteen control lines, two for each IGBT. Additionally, the bidirectional IGBT can be used in a precharge circuit of a power inverter or in a dynamic brake associated with a motor controller.
