Is IGBT a photovoltaic inverter

IGBT (Insulated Gate Bipolar Transistor) is an electronic switch that performs the key functions to convert direct current from the solar cells to an alternating current in solar inverters. In the solar energy sector, when discussing inverters with many technical folks, the topic of IGBT is almost inevitable.

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.

For this reason, they are often used as switching devices in AC/DC inverters circuits for motor drive systems, uninterruptible power supplies, and other applications. IGBTs are also often found in solar inverters, where they perform the key function of converting DC from solar cells to the AC required by various electrical equipment.

An IGBT (Insulated Gate Bipolar Transistor) is different from a power transistor in that it is controlled by the voltage applied to its gate rather than the current flowing into its base. The current flowing in the gate of an IGBT is extremely small because the impedance of the control gate is very high.

Both ends of the IGBT drive power supply in the photovoltaic inverter will bear this high voltage, so the IGBT drive power supply must be the reinforced insulation, and the isolation voltage should be high. On the other hand, the high voltage at both ends of the driving power supply exists for a long time.

In addition, IGBT drive power supplies provide reliable electrical isolation so that the control system can not be affected by the interference often caused by IGBT. However, despite the several advantages, there are still some challenges to consider concerning the application of IGBT technology in power modules.
