SIDAC the line voltage. Diode D1 is therefore necessary to provide a current path for charging C. C 3 VFD 400 V On the first half-cycle, C resonant charges through R 68 k OHMS 112 WATT diode D1 to a peak voltage of about 210 V, and remains at that value because of the blocking action of the rectifier PTC
