  • Publication number: 20250105730
    Abstract: A bidirectional isolated high voltage DC-DC converter includes a primary three-level circuit, a capacitor-inductor-inductor-capacitor (CLLC) resonant tank network connected to the primary three-level circuit, a secondary three-level circuit connected to the CLLC resonant tank network, and a controller that controls one or more of the components of the bidirectional isolated high voltage DC-DC converter. The primary three-level circuit and the secondary three-level circuit include capacitor middle points having respective voltages that are actively controlled by the controller. The controller implements a novel space vector PWM (SVPWM). The secondary capacitor middle point is chassis grounded to provide an optimal system level partial discharge hazard management for aircraft. vehicle and vessel applications. GaN power MOSFETs are used for high frequency operation of the power switches.
