Abstract
A power supply to operate fluorescent or mercury vapor lamps from 300-volt DC coal mine trolley wires was developed for the Bureau of Mines. A high-frequency regulated inverter unit incorporates ballasts for a mix of lamp loads up to 650 watts. For 600-volt trolley systems an additional power converter unit was developed to step down the DC voltage to 300 volts for the inverter unit. Both units have operated in a working coal mine for more than 12 months without need of servicing. The lamp load included two 100-watt mercury vapor head lamps and six 75-watt fluorescent lamps.
