Integrated circuits (ICs) are the core of energy conversion, management, and utilization in the new energy industry, directly affecting energy utilization efficiency and system safety.

In the field of new energy, IC is mainly used in the following areas:

·Power generation (photovoltaic/wind power): Power semiconductors (IGBT, SiC, MOSFET) form the core of photovoltaic inverters and wind power converters, responsible for converting crude electricity into high-quality grid connected electricity. Silicon carbide devices can significantly improve power generation efficiency due to their high voltage resistance and low loss.

·Transmission (Ultra High Voltage/Grid): High voltage power ICs and control chips are used for converter valve control in high-voltage direct current transmission, as well as relay protection and smart meters in the grid, to ensure long-distance low loss transmission and grid stability.

·Energy storage (battery): The battery management chip is the core of energy storage systems and electric vehicles, responsible for real-time monitoring of battery voltage and temperature, accurate calculation of battery capacity, and balanced protection, directly determining battery life and safety.

·Electricity consumption (automobiles/equipment): In electric vehicles, the main drive inverter module controls the motor, and silicon carbide devices are replacing traditional silicon-based IGBTs to improve endurance; Various microcontrollers and power management chips are responsible for vehicle thermal management, window control, and efficient power supply.

In addition, third-generation semiconductors (silicon carbide SiC, gallium nitride GaN) are becoming a key technology in the field of new energy due to their high voltage, high frequency, and high temperature resistance characteristics, which can significantly improve the power density from charging stations to vehicle end electric drive systems.
