INVERTER AND INVERTER CONTROL METHOD

Abstract

An inverter, an inverter control method, and a system. When the plurality of direct current boost circuits operate in a maximum power point tracking (MPPT) state, if input voltages of n direct current boost circuits in the plurality of direct current boost circuits are each greater than or equal to a first threshold, a controller controls switching transistors in m direct current boost circuits in the n direct current boost circuits to remain turned off. m and n are integers greater than 0 with n≥m. The first threshold is greater than or equal to a minimum voltage limit of the direct current bus.
