Design of single cycle current control method based on single-phase full bridge inverter circuit

Abstract

To achieve accurate control of the large inductive load, a single-phase full bridge inverter circuit topology with a simple structure is proposed. The current control on inductive load is realized by using the single-cycle control method, and the size and direction of the current can be adjusted at any time. The loading part is equivalent to the coil and resistance, the control principle of the circuit is analyzed, and the calculation formula of the duty cycle is calculated. The simulation results show that the designed circuit structure can control the current with a large inductive load
