| Summary: | 碩士 === 國立臺北科技大學 === 電力電子產業研發碩士專班 === 102 === The purpose of this thesis is to build a single phase BOOST type Power
Factor Corrector in order to a speed control system of a SRM motor driver. The front
stage employs a single-phase boost type AC/DC converter, which provides the
inverter stage with steady DC voltage. Then, a SRM motor is driven by the inverter
to accomplish the motion control. The AC-DC converter control the perfect duty of
power switch, so that the low-distortion and high-power-factor line current is
obtained. The controller consists of current, voltage loop and load-current injection
with parameters determined through Bode plot method. The model of the proposed
system has been established and simulated by Matlab/PSIM. The system is
implemented by the digital signal processor (TMS320F2812). This controller
supplies pulse-width modulation signals to the power switches of PFC stages, and
handles the PWM command and feedback current and voltage signal. Both the
simulation and experimental results are obtained to show the proposed system.
The specifications of a single-phase boost type PFC include: input voltage =
110±15%, output voltage = 200 V, and maximum output power = 600W. The single
phase BOOST type PFC is implemented using the TI DSP
(TMS320F2812) .Experimental results show that the power factor reaches 0.9 under
full load condition and efficiency is up to 96% as input voltage varied.
