Patent ID: 7525455

Claim:
A digitally actuated resonant power (DARP) converter comprising: a dithered first order multi-level quantized noise-shaping encoder for receiving digital data at a clock rate Fc/L1, where L1 equals 2 or more and Fc is a carrier frequency, and encoding the digital data; a power supply, having a frequency at or substantially near DC; a resonator having a resonant frequency at or substantially near the carrier frequency Fc; a load impedance coupled to the resonator for receiving energy stored in the resonator; and a charging switch, the charging switch coupled to the first-order noise-shaping encoder, the power supply, the resonator, and a clock having a clock rate (L2)(Fc), where L2 equals 2 or more, the charging switch adapted to: (i) receive encoded data from said first-order noise-shaping encoder; (ii) sample the voltage or current of said power supply; and (iii) deliver said power supply voltage or current samples to said resonator.
