440 VAC, Single Phase, Off-Line, 1.5 KW, Active PFC Front End Converter
Middletown, PA, July 2005 – Advanced Conversion Technology has developed a circuit topology that operates directly off the 440 VAC (50 to 400 Hz) power mains. This topology eliminates the need for a large, heavy multi-pulse step down transformer and includes an active PFC front end that insures low harmonic distortion, at any load level. With an output voltage of +270 VDC efficiencies greater than 85% are achievable. Input to Output Isolation is achieved magnetically and optically.
The +270 VDC output voltage can be used to supply the input voltage to industrial standard DC-DC converters to provide a range of output voltages. Other output voltage levels are available through transformer selection. For additional information contact us.
