“…Overvoltage should be limited because it may cause or accelerate the damage to these loads over time [32]. The causes of voltage overshoot generation in PSM power supplies have been analyzed [33]. When the SPS is not yet outputting current, the capacitance voltage of the SPS is the peak value of the transformer line voltage.…”

“…Compared with the previous scheme, a soft-start resistor R soft and switch S 2 are added. The specific circuit working process and parameter design are shown in [33]. The results show that the voltage overshoot suppression effect of the new module is significant, which can be reduced from 10.7% to 0.7%.…”
