Aug 1, 2008 · For solar inverter applications, it is well known that insulated-gate bipolar transistors (IGBTs) offer benefits compared to other types of power
As a power device, IGBT (insulated gate bipolar transistor) plays the role of power conversion and energy transmission in the inverter, and is the heart of the inverter. At the same time, IGBT is one of the most unreliable components in the inverter, which is very sensitive to the temperature and current of the device.
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.
For solar inverter applications, it is well known that insulated-gate bipolar transistors (IGBTs) offer benefits compared to other types of power devices, like high-current-carrying capability, gate control using voltage instead of current and the ability to match the co-pack diode with the IGBT.
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.
This series of DC/DC converters for IGBT drivers have all reinforced insulation. The isolation voltage reaches 5kVAC, and the partial discharge voltage reaches 1700V, which meets the high isolation requirements of photovoltaic inverter IGBT applications.
IGBT drivers are at the heart of IGBTs, as they generate gate signals used to turn on and off the IGBT according to the command signals from the control circuit. IGBT gate drivers also usually provide the electrical isolation which is often needed between the control circuit and the power stage.
