Undervoltage is also a problem that we often encounter in application. Mainly because the voltage of the main circuit is too low (220V series is lower than 200V, 380V series is lower than 400V), the main reason: a certain way of the rectifier bridge is damaged or there is abnormal operation in the three ways of the thyristor, which may lead to the appearance of undervoltage problems, ...

The preparation of the braking resistor of the inverter is mainly to consume part of the energy on the DC bus capacitor through the braking resistor to avoid the capacitor voltage being too high. Theoretically, if the capacitor stores a large amount of energy, it can be used to release it to drive the motor and avoid energy waste. However, the capacitance of the capacitor is ...
