摘要
提出了一种基于脉宽调制(PWM)的准谐振零电压开关(ZVS) DC - DC变换器控制直流电机速度的新方法。这种控制最大限度地减少了开关损耗，消除了电磁干扰(EMI)，提高了电机的效率和换相能力。通过控制准谐振变换器(QRC)谐振电感的自由转动周期来实现速度控制。半波(HW)恒频(CF) ZVS变换器的导通时间与平均输出电压呈非线性关系。因此，设计了一种模糊速度控制器，以获得更好的负载性能。仿真采用PSPICE A/D软件包。
A fuzzy based speed controller for soft switched DC to DC converter fed DC servomotor for aero space applications
A new method of speed control of DC motors using pulse width modulation (PWM) based quasi-resonant (QR) zero voltage switching (ZVS) DC to DC converters is proposed. This control minimizes the switching losses, eliminates electromagnetic interference (EMI) and improves efficiency and commutation capability of the motor. The speed control is achieved by controlling the free wheeling period of the resonant inductor of a quasi-resonant converter (QRC). A half wave (HW) constant frequency (CF) ZVS converter exhibits a nonlinear relationship between its ON time and average output voltage. Hence, a fuzzy speed controller is designed to get better performance under load conditions. The software package PSPICE A/D is used for simulation.
