CM6802A/B/AH/BH (Dynamic Soft PFC/Green PWM)

EPA/80++ ZVS-Like PFC/PWM COMBO CONTROLLER

Design for High Efficient Power Supply at both Full Load and Light Load

TYPICAL PERFORMANCE CHARACTERISTIC:

PFC Soft Diagram :

Dynamic Soft PFC Performance @ Vin=110 Vac

Ch1 is 380V bulk cap voltage which is 100V/div.

Ch3 is Input Line Current which is 1A/div.

Input Line Voltage (110 Vac) was turned off for 40mS before reaching PWM Brownout which is 209Vdc. When the bulk cap voltage goes below

209V, the system will reset the PWM soft start. The result of the CM6802A/B/AH/BH Input Line Current has a clean Off and softly On even the

system does not reset PWM soft-start.

Dynamic Soft PFC Performance @ Vin=220 Vac

Ch1 is 380V bulk cap voltage which is 100V/div.

Ch3 is Input Line Current which is 1A/div.

Input Line Voltage (220 Vac) was turned off for 40mS before reaching PWM Brownout which is 209Vdc when Bulk cap voltage drops below

209V. When the bulk cap voltage goes below 209V, the system will reset the PWM soft start. The result of the CM6802A/B/AH/BH Input Line

Current has a clean Off and softly On even the system does not reset itself. The first peak current at the beginning of the On time is the inrush

current.
