As the revolution of renewable energy as well as transportation electrification progresses, the need for residential energy storage systems is increasing. A high efficiency DC-to-DC converter is usually required to exchange energy generated from renewable sources, such as solar panels, with a battery. The fast-switching speed and low RDS(on) of gallium nitride (GaN) FETs can help save energy by reducing power consumption inside the DC-to-DC converter. This article shows how to design a high efficiency 100 – 250 V to 40 - 60 V DC-to-DC converter.
