This chapter introduces an optimal multivariable control (OMC) strategy for IPT systems employing an asymmetric double-sided LCC (DLCC) network. The method integrates dual-side hybrid modulation and a primary-side switch-controlled capacitor (SCC) into a triple-phase-shift (TPS) control scheme to reduce reactive power and enhance efficiency. The influence of hybrid modulation and SCC tuning on system behavior is analyzed, and dual-side zero-voltage switching (ZVS) is achieved with minimal reactive power. A multivariable optimization model based on power-loss analysis determines the optimal control variables that minimize system losses. Coordinated modulation of the inverter, rectifier, and SCC effectively lowers RMS and turn-off currents, improving efficiency across light and heavy load conditions. Experimental comparison with the conventional TPS method verifies superior DC-to-DC efficiency from 0.2 to 2.2 kW, achieving up to 6.3% efficiency improvement.
