Everyone often encounters the problem of inverter over-voltage protection when dealing with inverter faults. The over-voltage of the inverter means that the inverter voltage exceeds the rated voltage. The over-voltage protection of the inverter is caused by the over-voltage of the inverter.
s the overvoltage protection (main circui ).1. Overvoltage Causes and Suppression MethodF g.3-1 shows the inverter circuit for one phase. The overvoltage is generated at the wiring inductance LS of the main circuit due to a sudden change in the m in circuit current when the IGBT is turned-off. Fig.3-2 shows a typical IGBT1 turn-
A high frequency inverter is a type of UPS (Uninterruptible Power Supply) that uses a microprocessor as its process control center. It employs software programming to control its operation, unlike traditional analog circuits.
n be reduced and overvoltage can be suppressed. ( between the electrolytic capacitor and the IGBTPlace the electrolytic capacitor as close as possible to th IGBT in order to reduce the wiring inductance. It is even more with low impedance.Adjustment of main circuitTo reduc the inductance, use thicker and shorter wires. It is al
