In this paper, it mainly investigates the relationship between switching frequency and measured currents of Hall effect sensor. How to effectively measure the current waveforms to improve the PWM switching control performance is the main subject of concern. A compensation circuit is designed to enlarge the operational range of Hall effect sensor, and the measurement error can be reduced without additional temperature sensor.
