Abstract
A resonant converter is described that includes at least one power switch. The at least one power switch is characterized by a non-linearity coefficient that is less than or equal to a first threshold and a figure-of-merit that is less than or equal to a second threshold. The figure-of-merit being associated with an on-resistance of the at least one power switch and an output charge of the at least one power switch.
Claims25
A resonant converter comprising:
- at least one power switch, wherein the at least one power switch is characterized by a non-linearity coefficient that is less than or equal to a first threshold and a figure-of-merit that is less than or equal to a second threshold, the figure-of-merit being associated with an on-resistance of the at least one power switch and an output charge of the at least one power switch.
A power circuit comprising:
- a resonant converter that includes at least one half-bridge, wherein the at least one half-bridge has an effective non-linearity coefficient that is less than or equal to five and a figure-of-merit that is less than or equal to eight Ohm*nC, the figure-of-merit being associated with an on-resistance of the at least one half-bridge and an output charge of the at least one half-bridge.
A system comprising:
- a power source configured to provide power;
- a controller unit;
- a load configured to receive the power;
- and
- a resonant converter configured to convert the power for the load, the resonant converter includes at least one half-bridge controlled by the controller unit, wherein the at least one half-bridge has an effective non-linearity coefficient that is less than or equal to five and a figure-of-merit that is less than or equal to eight Ohm*nC, the figure-of-merit being associated with an on-resistance of the at least one half-bridge and an output charge of the at least one half-bridge.
