This paper presents a compact High-Voltage Insulated Gate Driver Supply using a 1 MHz Constant Voltage (CV) LCC-S Wireless Power Transfer (WPT) system. To mitigate high-frequency switching losses, a novel capacitor-detuning strategy is proposed. This method achieves Zero-Voltage Switching (ZVS) by slightly reducing the primary-series capacitance to shape an inductive input impedance, eliminating additional passive components while strictly preserving load-independent CV characteristics. The experimental detuning ratio (7.3%) aligns closely with the simulation design (8.4%), demonstrating the high precision of the proposed analytical model. A prototype with a 50-mm isolation gap was validated to withstand the 23.8 kV worst-case stress of a 14-layer SSCB stack. Operating at 1 MHz, it delivers 209.7 W with a peak efficiency of 81.1% and a surface power density of 3.28 W/cm².
