  • Cascade power system with isolated Class-E resonant circuit
    Patent number: 9941799
    Abstract: A cascade power system includes a non-isolated buck converter in cascade with an isolated Class-E resonant circuit, where the Class-E resonant circuit operates at high frequency, for example 4 Mhz. Further, the non-isolated buck converter is configured as a current source coupled to the Class-E resonant circuit which provides a buck converter output voltage as input to the Class-E resonant circuit. The Class-E resonant circuit includes capacitive isolation for the cascade power system output.
    Type: Grant

  • Current controlled resonant tank circuit
    Patent number: 9893627
    Abstract: A cascade power system includes a non-isolated buck converter in cascade with an isolated Class-E resonant circuit, where the Class-E resonant circuit operates at high frequency, for example 4 Mhz. Further, the non-isolated buck converter is configured as a current source coupled to the Class-E resonant circuit which provides a buck converter output voltage as input to the Class-E resonant circuit. The Class-E resonant circuit includes capacitive isolation for the cascade power system output. The Class-E resonant circuit and the capacitive isolation are configured such that impedance matching for the resonant tank of the Class-E resonant circuit is independent of an output load condition.

  • Current controlled resonant tank circuit
    Patent number: 9515560
    Abstract: A cascade power system includes a non-isolated buck converter in cascade with an isolated Class-E resonant circuit, where the Class-E resonant circuit operates at high frequency, for example 4 Mhz. Further, the non-isolated buck converter is configured as a current source coupled to the Class-E resonant circuit which provides a buck converter output voltage as input to the Class-E resonant circuit. The Class-E resonant circuit includes capacitive isolation for the cascade power system output. The cascade power system further includes a feedback control circuit for regulating a system output voltage. A feedback signal is used to adjust a duty cycle of the buck converter, thereby adjusting a buck converter output voltage. The buck converter output voltage is provided as input to the Class-E resonant circuit.
