Abstract
A battery discharge regulator system based on the Superboost converter is presented, and the working principle of the Superboost converter is analyzed. In order to meet the developing requirements of high efficiency and high power density converters, GaN devices are applied to the Superboost circuit to increase the switching frequency of the circuit. Thanks to this, the weight and volume of the passive devices can be reduced, and the power density of the circuit can be increased. In high-frequency conditions, the device parameters of the circuit are designed, and the theoretical derivation of the circuit transfer function is carried out. Finally, simulation software is used to verify the rationality and feasibility of the design.
