Abstract :
The performance of the linear power supply used for the checker of electric meter is analyzed in this paper. The significance and scientific value of researching and developing the high-power, high-efficiency, energy-saving and long-life PWM power supply for program-controlled checker of electric meter is also stated. The technical difficulties of developing PWM power are analyzed in depth according to the technical index of the PWM power supply. Solving the technical difficulties is focused and the key technology scheme and experimental results are presented in details. Experimental results show that the designed power supply has achieved the expected goals.
