Abstract
The present invention relates to a voltage converter circuit for transforming a low voltage applied to its input into a higher output voltage at an output. The voltage converter circuit comprises at least one first to fourth controllable switch of a first type, which are connected to each other in the form of an H-bridge, which is arranged between the input voltage and a reference potential, and a transformer with at least one primary winding arranged in a transversal branch of the H-bridge, and with a secondary winding, at which a transformed voltage can be tapped for generating the output voltage. In parallel to at least one of the controllable switches at least one controllable switch of a second type is arranged, which is conductive without a control potential being applied. The secondary winding of the transformer is furthermore connected with the control inputs of the controllable switches for feeding back the transformed voltage.
