【Abstract】 The theory and character of Variable-frequency Variable-wide chopper of rising Voltage that is different from conventional CWVF and CFVW chopper are introduced in this paper.The system software and hard-ware are designed with the control core of DSP,and transistor IGBT high frequency as on-off device.The results of experiment prove that the system is simpler,quicker respond,higher control precision,and better capability.更多还原
