TABLE 2 DATA FOR DC POWER SUPPLY WITH FULL-WAVE RECTIFIER
The Fluke 8000A DMM was used to measure VT. The HP54600B CRO was used to measure V1(avg), V1(pp), V2(pp), and V3(pp). The Fluke 8010A DMM was used to measure the dc load voltages V2(avg) & V3(avg). The load current IL was calculated using IL = V3(avg)/RL. The current IL + IZ was calculated using IL + IZ = {V3(avg) - V1(avg)} ¸ {RF + RS}. The Zener Diode current was calculated using IZ = {IL + IZ} – IL.
