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.
