INVERTER AND INVERTER CONTROL METHOD

An inverter and an inverter control method. The inverter includes an inverter system and a controller. The inverter system includes an inverter circuit, positive and negative direct current buses, a bus capacitor, and a balancing circuit. The inverter is configured to: when a user connects to an unbalanced load, control the balancing circuit based on different magnitudes of voltage fluctuation generated by the unbalanced load for the bus capacitor, to implement a function of jointly sharing current fluctuation by the bus capacitor and the balancing circuit, and reduce design costs of the bus capacitor and the balancing circuit.
