**Switch-Mode Rectifiers on Motor Drives** 

Switch-mode rectifier (SMR) or called power factor corrected (PFC) rectifier (Erickson & Maksimovic, 2001; Mohan et al, 2003; Dawande & Dubey, 1996) has been increasingly utilized to replace the conventional rectifiers as the front-end converter for many power equipments. Through proper control, the input line drawn current of a SMR can be controlled to have satisfactory power quality and provide adjustable and well-regulated DC output voltage. Hence, the operation performance of the followed power electronic equipment can be enhanced. Taking the permanent-magnet synchronous motor (PMSM) drive as an example, field-weakening and voltage boosting are two effective approaches to enhance its high-speed driving performance. The latter is more effective and can avoid the risk of magnet demagnetization. This task can naturally be preserved for a PMSM drive

Generally speaking, a SMR can be formed by inserting a suitable DC-DC converter cell between diode rectifier and output capacitive filter. During the past decades, there already have a lot of SMRs, the survey for single-phase SMRs can be referred to the related literatures. Since the AC input current is directly related to the pulse-width modulated (PWM) inductor current, the boost-type SMR possesses the best PFC control capability subject to having high DC output voltage limitation. In a standard multiplier based highfrequency controlled SMR, its PFC control performance is greatly affected by the sensed double-frequency voltage ripple. In (Wolfs & Thomas, 2007), the use of a capacitor reference model that produces a ripple free indication of the DC bus voltage allows the trade off regulatory response time and line current wave shape to be avoided. A simple robust ripple compensation controller is developed in (Chen et al, 2004), such that the effect of double frequency ripple contaminated in the output voltage feedback signal can be cancelled as far as possible. In (Li & Liaw, 2003), the quantitative digital voltage regulation control for a zero-voltage transition (ZVT) soft-switching boost SMR was presented. As to (Li & Liaw, 2004b), the robust varying-band hysteresis current-controlled (HCC) PWM schemes with fixed and varying switching frequencies for SMR have been presented. In (Chai & Liaw, 2007), the robust control of boost SMR considering nonlinear behavior was presented. The adaptation of voltage robust compensation control is made according to the observed nonlinear phenomena. The development and control for a SRM drive with front-end boost SMR were presented in (Chai & Liaw, 2009). In (Chai et al, 2008), the novel random
