IGBTs (Insulated Gate Bipolar Transistors) are ideal for applications with bus voltages in the hundreds to thousands of volts. As minority carrier devices, IGBTs have better turn-on characteristics than MOSFETs in this voltage range, while having a gate structure very similar to MOSFETs for easy control. In addition, since there is no need for an integrated reverse diode, this gives manufacturers the flexibility to choose a fast "composite package" diode optimized for the application, as opposed to intrinsic MOSFET diodes, which have reverse recovery charge Qrr and reverse recovery The time trr increases as the rated voltage increases.

The photovoltaic inverter is a very important device in the photovoltaic system. Its main function is to convert the direct current from photovoltaic modules into alternating current. In addition, the inverter is also responsible for detecting the operating status of components, power grids, and cables, and communicating with the outside world. , system security housekeeper and other important functions. It takes more than two years to produce a brand-new inverter, and a lot of manpower and material resources need to be invested in R&D and testing in the early stage.
