Abstract:

This paper presents a brushless DC (BLDC) motor drive with power factor correction (PFC) for low power and high speed applications. In this study, the speed of the BLDC motor is controlled by adjusting the DC link voltage of the voltage source inverter (VSI). A novel PFC based Non-isolated Zeta Fly-back converter operating in discontinuous conduction mode (DCM) is used for controlling the DC link voltage of the VSI by exploiting single voltage sensor. Utilizing the zeta converter and its valuable property in reducing output current ripple and its inherently power factor correction capability and interleaving fly-back converter to zeta and using its high gain property, this converter can be a good choice for interfacing BLDC motors drive. The MATLAB/ SIMULINK environment is used to simulate the proposed model to achieve a wide range of speed control with near unity power factor at AC mains and improved PQ (Power Quality) based on IEC 61000-3-2 standard.

I. Introduction

Recently, the brushless DC (BLDC) motors have become more important because of their high efficiency, high torque per inertia ratio, minimum maintenance requirements, high reliability, and less electro-magnetic interference (EMI) problems [1]. The BLDC motor is a three phase synchronous motor having torque–speed characteristics similar to a conventional DC motor [2]. It is also known as electronically commutated motor since an electronic commutation based on rotor position is used [2]. This eliminates the noise, sparking and maintenance problems in the DC motors [3]–[5].
