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).
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.
The inverter’s IGBT is like its heart. It handles power conversion and energy transfer inside the inverter. JOEYOUNG uses high-quality IGBT modules in all their inverters, like the 3000W solar inverter and the 12V 2000W pure sine wave inverter.
It is very sensitive to the temperature, voltage and current of the device. In case of even a slight stand exceeding, it becomes incompetent and cannot be repaired. IGBT damage means the inverter must be replaced or overhauled. Therefore, IGBT is the key protection object of the power inverter. The above is the three modes of IGBT failure.
At the same time, IGBT is also one of the most unreliable components in the power inverter. It is very sensitive to the temperature, voltage and current of the device. In case of even a slight stand exceeding, it becomes incompetent and cannot be repaired. IGBT damage means the inverter must be replaced or overhauled.
Block diagram of an IGBT inverter with: Gate drivers, IGBT Module, current sensing techniques and AC motor load. The block diagram consists of several important blocks: The IGBT module consists of six IGBTs in three sets of two in series.
