Experimental Study of High-voltage Inverter based on Carrier Phase Shift Control

The topology of high-voltage inverter with power unit cascaded on the basis of the principle of carrier phase shift control is introduced.The method to make multi-channel SPWM pulses by the use of FPGA and DSP combining is proposed.FPGA is used to make the real-time multi-channel pulses to control the high-voltage inverter and oscilloscopes and transformers were used to test its output voltage and current waveforms.Test results show the feasibility of the main controller combined with the FPGA to generate multi-channel pulses.
