| Abstract: | For the dead band in AC/AC converter controller,a design method of both software and hardware is pre-sented.All the trigger pulses are created by DSP.The full digitalization of the system is completed.The self-commu-tation of the controller is achieved by intelligent utilization of two timers of DSP.The dead band of commutation is greatly reduced.The quality of output waveform is improved observably.The experimental result verify the outstanding effectiveness and precision of the controller. |
