AI Technical Summary
The heat dissipation problem of existing high-frequency transformers is difficult to solve effectively in high-temperature environments, and traditional temperature sensors suffer from serious measurement delays and electromagnetic interference, resulting in lag in response and making it impossible to achieve precise control of the winding coil temperature.
By combining a semiconductor cooling chip and a piezoelectric fan, the heat generation power and dynamic resistance are calculated by real-time acquisition of the current and voltage signals of the wound coil, and a feedforward correction signal is generated to achieve automatic heat dissipation control. By combining the resistance-temperature model of the wound coil and the transformer core loss model, the real-time heat generation power and temperature change rate are accurately calculated, and the basic cooling control signal and feedforward correction signal are generated.
It achieves real-time and precise control of the winding coil temperature, eliminates the delay and electromagnetic interference of traditional temperature sensors, significantly suppresses temperature overshoot, and ensures stable operation and long service life of the transformer under complex operating conditions.
