研究目的
To study a soft-start method to deal with the problem of excessive starting current of LED lighting load, so as to avoid various adverse effects.
研究成果
The zero-crossing soft-starting technology adopted in the marine lighting system has an improved significance, effectively suppressing the inrush current generated by the LED lighting load during the startup process, and ensuring the system of economy and reliability.
研究不足
The capability of current limiting is restricted due to the small value of NTC type current limiting resistors, generally 5~10 Ω (at 25 °C).
