Abstract
A device to produce alternating electric current of high frequency for power consumers such as fluorescent lamps, which includes the means of supplying a DC voltage nearly twice the size of the peak voltage of the alternating voltage input--with negligible loss of power--to the remainder of the circuit and thus reducing the intrinsic power consumption of the device as well as making it possible to supply the said power consumer such as the fluorescent lamp with a higher start voltage as well as a higher voltage in operation.
