    摘要: An embodiment pulse generator circuit comprises a first electronic switch coupled between first and second nodes, and a second electronic switch coupled between the second node and a reference node. An LC resonant circuit comprising an inductance and a capacitance is coupled between the first and reference nodes along with charge circuitry comprises a further inductance in a current flow line between a supply node and an intermediate node in the LC resonant circuit. Drive circuitry of the electronic switches repeats, during a sequence of switching cycles, charge time intervals, wherein the capacitance in the LC resonant circuit is charged via the charge circuit, and pulse generation time intervals, wherein a pulsed current is provided to the load via the first and second nodes. The charge and pulse generation time intervals are interleaved with oscillation time intervals where the LC resonant circuit oscillates at a resonance frequency.
