Abstract
A method and an apparatus for converting a three phase input into a constant voltage to a load, which voltage is substantially free of harmonics and ripples includes dividing the voltage to the load into two component voltages, with one component voltage comprising at least 80% of the total. The one component voltage is maintained constant and load independent. The voltage to the load is compared to a first reference voltage to obtain the difference therebetween and the value of the other component voltage is adjusted to minimize the difference. The two component voltages are added to form the voltage to the load.
