Title: Power supply
IPC: H02M5/458
Filed: 1989-09-14
Abstract: An inverter power supply with improved power factor 
comprises a source of low frequency AC voltage and an 
inverter having a pair of series connected first and second 
transistors controlled to alternately turn on and off at a 
high frequency for providing a high frequency AC voltage to 
a load. A diode-bride full-wave rectifier is connected to 
provide a DC voltage which is charged to at least one 
capacitor which in turn provides a DC voltage input to the 
inverter. An inductor, which counteracts the capative 
reactance of the capacitor for improving the power factor, 
is inserted in series with the AC voltage source across the 
input of the diode-bridge rectifier. The first and second 
transistors of the inverter also operate to interrupt or 
chop at the high frequency a current fed through the 
inductor from the AC voltage source so as to charge the 
capacitor through the rectifier by the inductor. During 
each one cycle of the AC voltage from the AC voltage source, 
the first and second transistors are both serve to chop the 
current through the inductor for charging the capacitor as 
well as to provide the current to the load. Further, the 
rectifier shares at least two diodes of the inverter for 
establishing a loop for charging the capacitor.
