Research on a novel modulation technology for high-frequency link inverter

A novel control method for high-frequency link inverter is given in this paper. The control principal is described in details, and the digital control signal generating method based on DSP is analyzed. The experimental results indicated that the digital control method is simple reliable and general, the output waveform of high-frequency link inverter is sine-wave, and the switches of power circuit can be realized with soft switching. The experimental results proved the control method is feasible.
