Electrical matrix converter has two groups of part cells used for positive and negative current in supplying electrical drives

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention is an electrical matrix converter composed of multiple converter stages, each including a diode and an insulated gate bipolar transistor (IGBT). The converter is designed so that half of the stages are dedicated to handling positive electrical currents, while the other half handle negative currents. This matrix converter connects to an electric motor through a transformer to efficiently control the supply of electrical drives.

Patent Abstract

The electrical matrix converter is based upon part converter stages that have a diode in series with such as an insulated gate bipolar transistor, IGBT. An even number of stages are used whereby half are used only for positive electrical currents and the others are used for negative electrical currents. The matrix connects via a transformer to a motor.
