Assessment of Pulse-Width Modulation Techniques for Brushless DC Motor Drives

Yen‐Shin Lai, Yong-Kai Lin

Abstract

The purpose of this paper is to assess the pulse-width modulation (PWM) techniques for brushless DC motor (BLDCM) motor drives. The criteria for assessment include driver circuit, reversal DC-link current, circulating current of floating phase, and back electro-magnetic force (EMF) detection. The advantages and disadvantages of five PWM techniques for BLDCM drives will be analyzed and confirmed by experimental results. The results presented in this paper are expected to provide whole picture for applications reference
