Limit circuit fault.

The short-circuit fault ride-through capability of the inverter directly affects the reliability of the independent power supply system under short-circuit faults. Many existing short-circuit current-limiting strategies of three-phase inverters only ensure that the inverter outputs the fault current to trip the faulty branch circuit breaker during the fault period. …

Voltage-controlled three-phase three-leg inverters are widely applied in various occasions. The inverters are generally switched to the current-controlled mode to limit the fault currents when short-circuit faults happen. Under symmetrical fault, the inverter can be controlled as a symmetrical, three-phase current source. However, the … Furnace turns on and will ignite then the gas immediately shuts off and the blower remains on.
