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

A resonant power converter for converting a DC input voltage to AC or DC output voltage, includes a transistor, and a first inductor connected to an input port for a DC voltage to be converted, the drain being connected to the input port by way of the first inductor, the converter furthermore comprising a first resonant network, connected between the drain of the transistor and ground, the first resonant network being configured so as to extract the fundamental component of a drain-source voltage of the transistor and to phase-shift it by a phase shift angle such that the fundamental component and the drain-source voltage are in phase opposition and thus generate a sinusoidal drive signal.
