| Abstract: | Through analysis and research on the working mechanism of producing PWM outputs and dead-time delay by 87C 196MC single-chip-computer＇s waveform generator, a novel PWM control method is presented to control the bridge DC/DC converter with regulating the dead-time. Both programming principle and theoretical analysis are expatiated. This method with high resolution and large duty-cycle regulating range is easy to program and occupy a little working time. The correctness and feasibility of the method are confirmed by experimental results on prototype of constant potential instrument for cathode anticorrosion protection. |
