After the load is applied, the DC voltage after rectification is low, causing undervoltage failure. Countermeasure: Check whether the circuit breaker or contactor contacts of the inverter power supply are in good contact, whether the contact resistance is too large, whether the input voltage is normal, etc.
1. Power supply phase loss Cause: When the inverter power supply phase is lost, the three-phase rectification becomes two-phase rectification. After the load is applied, the DC voltage after rectification is low, causing undervoltage failure.
This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on. Check supply voltage for constant or transient high voltage. Increase deceleration time.
Why is the output voltage of a rectifier always greater than input voltage..connecting a low pass filter also increases the voltage furthermore Your meter may be reading the peak voltage of your output when measuring DC voltages. The peak voltage of a sine wave is about 1.4 times the RMS voltage. The filter capacitor charges to the peak voltage.
Another possible cause could be an inadequate power source or improper electrical connections. Faulty wiring can also result in voltage fluctuations. If you are experiencing inverter low voltage problems, it's essential to diagnose the issue accurately. Start by checking the battery health.
One of the most common reasons why an inverter generator produces low power is due to a high load. Inverter generators are designed to produce power based on the load, and if the load is too high, the generator will produce low power.
