如何降低VIPER17启动电压？

你好，


我想在宽整流电压范围（从50 Vdc到380 Vdc）下操作反激式转换器。

有没有办法降低VIPER的反激启动电压？虽然可以停用布朗输出保护并且反激可以在50VDC整流电压下有效工作（我已经测试它并且它确实正常工作），但是不可能在低电压下启动驱动器。

任何建议，外部加电威廉希尔官方网站 建议将不胜感激。

Hello,


I would like to operate a flyback converter at a wide rectified voltage range (from 50 Vdc to 380 Vdc).

Is there any way to reduce the Flyback start-up voltage of a VIPER? Although the Brown out protection can be deactivated and the flyback can effectively work at 50VDC rectified voltage (I have test it and it does work properly), it is not possible to start the driver at low voltage.

Any recommendation, external power-up circuit suggestion would be greatly appreciated.

Ernest
