With the development of industry, more and more energy consumption has brought about a huge crisis. The development of renewable energy technologies, such as photovoltaic equipment, offers new hope for solving energy problems. Solantro SFnG has been developed and operated in the company’s lab for about 5 years. This real-life nanogrid contains PV panels, energy storage units, a variety of loads and the micro-chip controller.
In the development of power electronic devices, more and more switch mode power supplies (SMPS) are used in various fields. SMPS transfer power from a DC or AC source to DC loads. And they have many advantages, such as high conversion efficiency, low energy loss, and lighter weight than linear power supplies. However, switching current in SMPS can cause electrical noise problems and it may have a poor power factor. To solve these problems, gallium-nitride (GaN) based Totem-Pole power factor correction (PFC) has been used.
