Abstract
In a voltage regulator converter circuit comprising an input 20 and an output 25, an input signal can be controlled by applying a high frequency switching signal (1 KHz-30 MHz) to an input circuit 12, 13, 16 and 17. An output of the circuit is obtained via an inductor 28 and a capacitor 29. The input can be DC to 500 Hz and the output can be DC or AC. Switches 12, 13, 16 and 17 can be thyristors, bipolar transistors, field effect transistors or IGBi transistors. Diodes 11, 14, 15 and 18 are connected in series with the switches 12, 13, 16 and 17. In an alternative embodiment (FIG. 9) the four switches can be connected in series between an AC input and an output is obtained from a center point of the series connection via an inductor (106) and a capacitor (107). A further aspect (FIG. 10) relates to transformed coupled input and output switching stages.
