Re:Used to convert the direct current generated by solar panels into alternating current for use in households or the power grid. Used to control the start, stop, and energy conversion of wind turbines. The thyristor/diode module plays an important role in the rectifier switch circuit of the inverter and the inverter of the wind power system. With the development of new energy, energy storage systems have become increasingly important. Thyristor/diode modules have a wide range of applications in charging and discharging control of energy storage systems. With the expansion of the electric vehicle market, the demand for charging facilities is constantly increasing. The thyristor/diode module plays a crucial role in the power module, charging control, and energy recovery system of charging facilities.
