【Abstract】 Fully digitalized control with a single chip microcomputer for current source inverter is investigated.Three chips of microcomputer are used to perform three different functions, the first for dual PID controller in voltage and current loops, the second for pulse-triggered circuit in the thyristor converter and the third for the nonlinear function generation and ring counter in the inverter.With fully digitalized control, the current source inverter is of higher reliability and simpler system structure.更多还原
