AC input overvoltage and undervoltage protection

Supply ZTE zxd3000 (V5.0) communication power module 48V 50A

The module design has a very wide input voltage range (80V AC ~ 300V AC) and the detection of over-voltage and under-voltage of the circuit is only used as the basis of protection, while the detection of AC input voltage is still based on the situation of sine wave or small waveform distortion. At this time, the average value of full wave rectification is used for AC voltage detection, and the sampling point of AC input voltage is before the slow start of AC input.

Supply ZTE zxd3000 (V5.0) communication power module 48V 50A

The overvoltage and undervoltage protection and power reduction control scheme of ZTE zxd3000 (V5.0) AC input are as follows:

1. The starting voltage of auxiliary power supply is ≤ 70V AC. Supply ZTE zxd3000 (V5.0) communication power module 48V 50A

2. When AC input ≤ 80V AC, turn off the PFC and DC / DC of rectifier.

3. When 80V AC ≤ AC input ≤ 110V AC, the current limiting point IMAX = (10 ± 2) a.

4. When 110V AC ≤ AC input ≤ 150V AC, the current limiting point IMAX = (20 ± 2) a.

5. When 150V AC ≤ AC input ≤ 300V AC, the current limiting point IMAX = (32 ± 1) a.

6. When AC input ≥ 300V AC, turn off the PFC and DC / DC of rectifier.

All the above functions are realized by hardware. The accuracy of voltage error is ± 10V and the hysteresis width is (15 ± 10V)
