Abstract
A converter includes a resonant oscillatory tank circuit comprising a capacitor and an inductor, at least one switching circuit including a solid state switching device in series with a diode connected to apply a predetermined potential difference from a DV supply to the inductor, and synchronizing means responsive to the oscillation of the oscillatory circuit for switching on the switching means for a fraction of a cycle only when the instantaneous value of the oscillatory potential difference across the inductor is already not less than a predetermined value, to delay the fall of the said oscillating potential difference and inject energy from the supply into the oscillatory circuit, and a load circuit coupled or connected to the tank circuit.
