Typically, a three-phase IGBT-based PWM inverter stage with voltage DC-link (voltage source inverter, VSI) is employed for supplying the electrical machine. The switching losses of the IGBTs and anti-parallel freewheeling diodes are limiting the switching frequency to val-ues of fs < 16 kHz, which is still within the audible range.
As an essential circuit topology structure in the motor control system of the test platform, the three-phase IGBT full-bridge inverter circuit must improve its simulation model''s calculation efficiency and accuracy.
An inverter is a power electronic conversion circuit which converts DC supply into AC. Therefore, three-phase inverter converts DC into three-phase AC . Single-phase VSI s cover low-range power applications and three-phase VSI s cover the medium- to high-power applications.
IGBTs are used in many different power electronic devices, particularly in power conversion systems like motor drives and industrial equipment. Due to their ability to switch high voltages and currents efficiently, a power inverter is a very interesting topic for IGBTs. An inverter converts direct current (DC) into alternating current (AC).
