Abstract:
The invention relates in a first aspect to a resonant power converter comprising: a first power supply rail for receipt of a positive DC supply voltage and a second power supply rail for receipt of a negative DC supply voltage. The resonant power converter comprises a resonant network with an input terminal for receipt of a resonant input voltage from a driver circuit. The driver circuit is configured for alternatingly pulling the resonant input voltage towards the positive and negative DC supply voltages via first and second semiconductor switches, respectively, separated by intervening dead-time periods in accordance with one or more driver control signals. A dead-time controller is configured to adaptively adjusting the dead-time periods based on the resonant input voltage.

Claim (Index 17):
A method of adaptively controlling a dead-time interval of a driver circuit of a resonant power converter, comprising steps of:\n generating first and second non-overlapping driver control signals for the driver circuit in accordance with a switching frequency of the resonant power converter, wherein the driver circuit is coupled between positive and negative DC supply voltages for supply of power, applying the first and second non-overlapping driver control signals to the driver circuit to generate a driver output signal alternating between the positive DC supply voltage and negative DC supply voltage separated by intervening low to high dead time periods and high to low dead time periods, applying the driver output voltage to an input section of the resonant network to generate a resonant input voltage, generating a resonant output voltage in response to the resonant input voltage at an output section of the resonant network, detecting a feature of the resonant input voltage, adjusting durations of the low to high dead time periods based on the detected feature of the resonant input voltage and independently adjusting durations of the high to low dead time periods based on the detected feature of the resonant input voltage.
