On-line UPS application mainly includes the four functional sections of ¡°PFC¡±, ¡°Charging¡±, ¡°Boosting¡± and ¡°inverter¡±
¡ñ PFC: driven by high voltage DMOS transistor
¡ñ Charging: driven by high voltage DMOS transistorspan
¡ñ Boosting: driven by low voltage DMOS transistor
¡ñ Invertor: driven by high voltage DMOS transistor
