摘要： An inductive power supply that maintains resonance and adjusts duty cycle based on feedback from a secondary circuit. A controller, driver circuit and switching circuit cooperate to generate an AC signal at a selected operating frequency and duty cycle. The AC signal is applied to the tank circuit to create an inductive field for powering the secondary. The secondary communicates feedback about the received power back to the primary controller. The power transfer efficiency may be optimized by maintaining the operating frequency substantially at resonance, and the amount of power transferred may be controlled by adjusting the duty cycle.

In one embodiment, the dynamic communication load configuration vanes as a function of a characteristic of power in the remote device. The remote device toggles between load configurations to communicate with the inductive power supply. A sensor in the remote device detects a characteristic of power in the remote device and configures the communication load based on the sensor output. In another embodiment, the remote device adjusts the dynamic communication load configuration in the remote device in response to a failure to receive a response from the inductive power supply.

摘要： An inductively powered gas discharge lamp assembly having a secondary circuit with starter circuitry that provides pre-heating when power is supplied to the secondary circuit at a pre-heat frequency and that provides normal operation when power is supplied to the secondary circuit at an operating frequency. In one embodiment, the starter circuitry includes a pre-heat capacitor connected between the lamp electrodes and an operating capacitor located between the secondary coil and the lamp. The pre-heat capacitor is selected so that the electrical flow path through the pre-heat capacitor has a lesser impedance than the electrical flow path through the gas of the lamp when power is applied to the secondary circuit at the pre-heat frequency, and so that the electrical flow path through the pre-heat capacitor has a greater impedance than the electrical flow path through the gas when power is applied the operating frequency. The primary circuit may include a tank circuit for which the resonant frequency can be adjusted to match the pre-heat frequency and the operating frequency.
