In order to maximize the utilization of solar energy under various irradiation conditions, the combination of multiple micro inverters (<1kW ) for power supply, or multiple power optimizers and a kW class PV inverter are increasingly used in residential PV systems.
LFG has developed KF9 MN-Zn ferrite material with wide frequency, wide temperature and low core loss to meet the application requirements of household photovoltaic inverters. Under the conditions of 100~300kHz and 25~120℃, it has excellent characteristics of low core loss and high saturation flux density, which is especially suitable for making transformer in high-frequency power conversion circuits of photovoltaic inverters.
