WebSeveral approaches for improving the filter performance at high frequency are conducted. With these approaches applied, a single-stage filter is demonstrated in an off-line 1 kW, 12 V server power supply. Thus, for the first time, a single-stage EMI filter can be contemplated to meet the EMI standard in server power supplies. WebAnswer (1 of 13): Yes, but only once and only for an instant. A transformer only responds to changing magnetic fields, like those found in AC signals.
