摘要：Hysteresis current controller is used in many industrial applications because it has many advantages as fast, high dynamic performance and doesn’t require any information about load parameters. The draw back of this current controller is varying switching frequency. This paper presents adaptive hysteresis current controller to control the inverter. It is used to reduce the ripple, total harmonic distortion and improvement the switching frequency through design of PI current controller. The performance of the drive system due to improvement in the hysteresis current controller is simulated through the matlab simulink. The modified hysteresis current controller is compared to conventional hysteresis controller under steady state and transient conditions with fixed load, sudden applied and sudden removal load and reversing load to show the effectiveness of this modification.
