Abstract
An inverter arm is made up of two transistors electrically connected in series, each transistor having its own independent control unit. The control units are supplied by a common power supply unit ensuring galvanic insulation by means of a transformer with two distinct secondary windings. This galvanic insulation allows a potential difference of several hundred volts between the transistors and their control circuit.
