Using the Power Supply, Synchronizing Switch, AC Metering and DC metering Modules connect the circuit shown below. Note that the fixed 120 Volt AC source is connected across one lamp and the variable DC source is connected across the adjacent lamp. Vac = 120 V rms. Vdc = _____ Volts dc Turn on the power supply.

The basic requirements of the proposed power supply are as follows. The AC input voltage to the DC power supply is variable providing a maximum voltage and current of 1000VAC at 5A RMS, respectively. The proposed industrial power supply DC voltage is required to regulate its DC output to 50 Volts DC with a maximum current rating of 20 Amps.

In practice DC power for electronic circuit is most conveniently obtained from commercial AC lines by using rectifier-filter system, called a DC power supply. The rectifier-filter combination constitutes an ordinary DC power supply. The DC voltage from an ordinary power supply remains constant. So long as AC mains voltage or load is unaltered.

As mentioned above, a 3 phase DC/AC inverter used in traction is supplied by a power net that can be either DC or mono-phase AC. In the case of AC supply, the (mono-phase) net is connected to the three-phase DC/AC inverter through a transformer and an AC/DC rectifier The connection line between the rectifier and the inverter is called DC link.
