A power converter for converting a DC input voltage into an AC output voltage, the power converter having a structure of Phi-2 type, and includes an input terminal for the DC input voltage, an output terminal for the AC output voltage, a power switch equipped with a control electrode, a first electrode and a second electrode linked to a reference potential, the power switch being configured to receive a drive signal at the control electrode, the converter further comprising a self-oscillating circuit, connected between the output terminal and the control electrode, and configured to supply and maintain a sinusoidal drive signal to the power switch from the output voltage.

Class Phi-2 power converter comprising a self-oscillating switch control circuit

The invention relates to a voltage converter (), including: a plurality of two-way conversion cells (), each cell comprising a primary circuit (, Wp), and a secondary circuit (, Ws) that is insulated from the primary circuit, wherein each circuit can be separately activated in order to supply an output voltage from the converter; and at least one control circuit () configured to, in a first operating mode, control the activated cells in order to transfer electrical energy from the primary circuit to the secondary circuit, and control the inactivated cells in order to transfer electrical energy from the secondary circuit to the primary circuit.
