Patent ID: 8441819

Claim:
A Buck-Boost Converter, comprising: first and second switch arrays, each comprising at least two bidirectional switching devices; a substantially parallel inductor-capacitor combination connected to each said switch array; and a link switch, connected across said inductor-capacitor combination in a crowbar configuration which includes a resistance element which is connected to dissipate energy stored in said substantially parallel inductor-capacitor combination when said link switch is on; wherein a first one of said switch arrays is operatively connected to a power input, and is operated to drive power into said inductor-capacitor combination with a non-sinusoidal waveform; and wherein a second one of said switch arrays is operated to extract power from said inductor-capacitor combination to an output; and wherein, when said link switch is on, said switch arrays are connected to totally disconnect said substantially parallel inductor-capacitor combination from said power input and said output.
