High frequency inverter front stage output

The high-voltage output generated by the front-stage transformer passes through the high-frequency transformer to output high-frequency alternating current, and then a high-frequency hundreds of V direct current is output to the back-stage mosfet/IGBT through the fast recovery diode full bridge rectification, and then the back-stage IC generates 50Hz control signal which is used to control the work of the mosfet/IGBT of the subsequent stage, and then output 120v/ 220v/ 230v/ 240v V 50/60Hz alternating current.

Energy storage battery capacity reduction in low temperature environment

However, LIBs usually suffer from obvious capacity reduction, security problems, and a sharp decline in cycle life under low temperatures, especially below 0 °C, which can be mainly ascribed to the decrease in Li + diffusion coefficient in both electrodes and electrolyte, poor transfer kinetics on the interphase, high Li + desolvation barrier in the electrolyte, and severe Li plating and dendrite.
