Technical FAQs 4

What is a power inverter (IGBT)?

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).

How does a 3 phase inverter work?

Pulse-width modulation (PWM) to the motor controls the output voltage. The three-phase inverter also uses six isolated gate drivers to drive the IGBTs. Apart from the IGBTs and isolated gate drivers, three-phase inverters include DC bus voltage sensing, inverter current sensing and IGBT protection like over temperature, overload and ground fault.

What are IGBT transistors used for?

Most three-phase inverters use insulated gate bipolar transistors (IGBTs) in applications like variable-frequency drives, uninterruptible power supplies, solar inverters and other similar inverter applications.

What is a three-phase inverter reference design?

Three-phase inverter reference design for 200-480VAC drives (Rev. A) This reference design realizes a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors.
