Manufacturer:ADI Description:gate, deactivating the gate drive circuits and shutting off the in- verter. The relay control circuit delivers an on/off signal via an opto-isolator to the relay driver which controls the relay (K1). The relay contact is open during power-up, inserting the resistor R in series with the DC bus capacitor and limiting the capacitor charging current. In normal operation, the relay contact is closed. If the AC line voltage falls below 300V or if one input phase is lost, or if the DC line voltage falls to less than 82% of the peak line voltage, the relay contact opens. The UV circuit senses the voltage of the local power supply, and sends a signal via an opto-isolator to the latch in the event of undervoltage. The UV circuit normally activates the latch only during power-up and power-down, preventing the IGBTs from |
