dc.description.abstractElectricity as a clean energy, the proportion of global energy supply is increasing year by year, with the rapid popularity of mobile robots, mobile robot applications for mobile robot power supply requirements, miniaturization, high reliability, high efficiency is the direction of people's needs. The purpose of this thesis is to research how a combination of a Totem-pole bridgeless PFC converter and an LLC converter can achieve a high-efficiency power supply operating at 500kHz, and to compare the stress and losses in the circuit between GaN and Si devices. From the experimental point of view, under the proposed topology, the operating loss of the Si device is higher than that of the GaN device (21.9868W and 4.1319W), and the power supply can reach 97.5% efficiency.en
