| Abstract: | A design method of three-phase intermediate frequency aerial power of 115 V/400 Hz based on DSP is pro-posed. The working principle and control method of phase-shifted full-bridge converter and cycloconverter are presented in detail. The overall structure of the system and the power circuit are also given. The phase-shift-controlled technology and the high- frequency (HF) link inverting technology are also adopted in the design of this power supply, which makes the circuit realize soft switching to the utmost extent. The experiment results verify the control methods are reasonable and with high reliability and power density. |
