The correspondence power switch is the telecommunication network energy, its power supply quality quality relates directly to the entire telecommunication network unimpededness, this topic has first analyzed the recent years domestic and foreign communications switching power supply development condition, tests in the theoretical analysis and the electric circuit in the foundation, developed one kind of new communication switching power supply (alternating-current distribution module, direct current power distribution module, 4 high frequency switches rectification module and monitoring module puts in identical rack), this power source optimized the electric circuit main parameter, has designed the phase-shift pulse-duration modulation zero potential switch resonance (PS-ZVS PWM) the entire bridge converter electric circuit and take integrates the controller UC3875 chip as the core control circuit, Realized the power switching valve zero potential to clear with the approximate zero potential shuts off, develops the high efficiency (to reach 93%), the high stability (±0.5%), redundant reliable, the low electronmagetic interference high frequency switch rectification module. At the same time in the article also proposed based on MCS-51 is the core power source monitoring module and monitoring design mentality. Has guaranteed entire machine safe reliable work.
