Whether implemented in distributed Power Optimizers, or as the first stage of a solar string inverter, Silicon carbide devices can enhance the efficiency and switching speed of the Maximum Power Point Tracking (MPPT) circuit to boost power into a constant, higher voltage to the internal bus.
Solar inverters are responsible for converting DC current into grid-ready AC current quickly, efficiently and with minimal energy loss. Using Wolfspeed Silicon Carbide in your inverter can significantly improve efficiency and drastically increase switching frequency resulting in smaller, lighter, lower cost systems.
Nowadays, silicon (Si)-based devices, including Si insulated-gate bipolar transistor (IGBT) and Si diode, are commonly used in inverters. However, over the past four decades, the performance of Si devices has reached its boundary . Recently, silicon carbide (SiC)-based devices are used to improve the performance of PV inverters .
