Power Converter Gating Signal Generation with DSP Software

DSP 소프트웨어에 의한 전력변환기 게이팅 신호 발생

Power converters are widely used in the applications of servo drives of ac and dc motors and power supplies. For the control of the converters carious control algorithms have been proposed and realized by gating signal generation. Software control shemes are being applied to implement the control algorithms, but analog circuits are still used for the gating signal generation because it requires very fast and precise timing. In this paper the gating signal generation with DSP software are proposed for the three phase to three phase PWM converter. Design procedures and software flowcharts are presented and some experimental waveforms are also presented to verify the proposed algorithms.
