However, hard-switched GaN half-bridges suffer from cross-conduction phenomena: the resonant coupling between HEMTs' drain-source capacitance and internal or external parasitic inductances cause a capacitive current to charge and discharge the output capacitance C ds of the low-side or high-side HEMT inducing high current peaks and shoot-through events, causing increased power dissipation, potential failure of the power stage, and elevated electromagnetic interference (EMI). This paper presents a circuit-level topological solution to address EMI and efficiency concerns through a dual interleaved GaN half-bridge architecture. The topology, driven by digital control logic, demonstrates a significant performance shift when transitioning from hard-switching to Zero Voltage Switching (ZVS) regimes, enhancing efficiency (peak at 99.13%) and effectively suppressing high-frequency oscillations.
