Estimating the term…
A power converter is proposed for converting a mains input into an output for driving at least one load, in particular for driving a pair of electrodes in a treatment chamber of a pulsed ohmic heating or other pulsed electrical fields technology (PEF) based cooking appliance, the power converter, also able to be put in use as a resonance converter, comprising a circuit at least composed of a rectifier unit arranged for receiving a mains input and for converting the mains input into a pulsating voltage, output for driving the load; at least one high frequency filter unit connected in a parallel branch with the rectifier unit; as well as a bridge inverter unit comprising at least one bridge branch connected in parallel with the rectifier unit and connected with the at least one load; wherein the at least one bridge branch comprises two switches connected in series, wherein an output terminal is provided between the two in series connected switches in the at least one bridge branch, the output terminal of the at least one bridge branch being connected with the load; and wherein a current injection unit is provided between the output terminal and the rectifier unit.
