电源设计（Power Design） 1 design requirements and specific circuit design The key part of the basic communication switching power supply system is switching power supply rectifier module. There are many specifications of the rectifier module. Combining the actual situation encountered in the work, the design of the module hard indicators are as follows: 1) the allowable voltage fluctuation range of the grid Editorial: for the design of switching power supply | pipeline ultrasonic cleaning machine without tuning the brick wall low pass audio filter | adaptive Q current control AB power amplifier circuit can meet the design | micromicroammeter fast intelligent charger, power consumption and cost | distortion can handle a wide range of voltage fast and stable (Figure) | reduced two test methods | in high performance CPU power component cost | new notebook computer power management technology | battery power supply circuit for electronic watt hour meter design |34063 | DC DC power converter Text: The single-phase AC input, RMS fluctuation range: 220 V + 20%, which is 176 ~ 264 V; frequency: 45 ~ 65 Hz. 2) DC output voltage, current The nominal output voltage: - 48 V, adjustment range: 43 ~ 56. 5V floating charge, 45 ~ 58V. The output current: rated value: 50A. 3) protection and alarm performance When the input voltage is low or high to 170 VAC to 270 VAC, or radiator of high temperature to 75 DEG, automatic shutdown. When the DC output voltage up to 60 V modules, or output current up to 58 ~ 60 A, automatic shutdown. When the output current is up to 53 ~ 55 A, automatic current limit load, continue to increase, lower output voltage. 4) efficiency and power factor The efficiency of the module is not less than 88%, the power factor is not less than 0.99. 5) other indicators The other performance of the module to meet the YD/T731 and network inspection rules for the implementation of industry standards such as 2. The Because the output power of the module is not large, the basi
