The 800v quasi resonant design with lower current peak and lower drain-source voltage during turning on of the MOSFET demonstrates advantages in conducted EMI spectra regarding the primary side.
The number of the selected thyristors to be assembled in series is different, which depends on the peakvoltage requirements of the grid used.
根据所使用电网的峰值电压要求，选择可控硅串联的数量不同。
