| Abstract: | A novel full digital three-phase sinusoidal pulse width modulation (SPWM) signal generation chip is presented for power electronics.A modified direct digital frequency synthesis(DDS),pipelined structure,and time-sharing ROM are adopted in the chip,for saving chip area and ensuring high performance and speed.The system clock is set at 24MHz,the output signals defined in 65536 equal steps cover a bandwidth from DC to 4kHz,and the multifunction is designed for control.The chip is fabricated by using charted 0.35μm COMS technology.The test results show that the chip achieves the design specification |
