ABSTRACT:
A hysteresis current controller includes a hysteresis current control device which has an adjustable hysteresis band. A feedback signal indicative of current in the load is compared with a current demand signal to produce an error signal which is received by the hysteresis control device. The switching output of the hysteresis control device is monitored to derive a signal indicative of its frequency which is used in a control loop to vary the hysteresis band to maintain the switching frequency output substantially constant.
