Abstract
An apparatus comprises a sense transistor having a gate and a source directly connected to a gate and a source of a power transistor of a resonant converter respectively, wherein the resonant converter comprises a primary side and a secondary side magnetically coupled to the primary side, a current sense and amplification circuit comprising an amplifier having inputs connected to a drain of the sense transistor and a drain of the power transistor respectively, an analog-to-digital converter connected to an output of the current sense and amplification circuit and a digital controller connected to an output of the analog-to-digital converter, wherein the digital controller is configured to modulate a variable capacitance network of the resonant converter based upon a current flowing through the sense transistor.
