| Abstract: | This paper focuses on a high-frequency link inverter with full-bridge inverter -cycloconverter as its main circuit topology and DSP as its core controller. The fundamental principles of the sinusoidal pulse width modulation control strategy and the control method is described.Then ,the implementation scheme of the control strategy based on DSP is introduced. PSIM is used on the digital simulation of the system and a principle test device is designed.The simulation and experimental waveforms is gived at last. The research results show that this inverter has good static and dynamic performance by digital control, good waveform quality, small THD, and the voltage loop has good following performance. |
