Working type of repeater power adapter
There are 3 working states.
Class A, the on-time is fixed, and the off-time is variable.
Type B, the turn-off time is fixed, and the turn-on time is variable.
Type C, the turn-on and turn-off time are variable, and the rate (frequency) is fixed.
The main differences in performance of these types are as follows.
At light load, Class A will work at a very low frequency.
When the load is maximum, Class B will work at low frequency.
Class C has more ideal characteristics, because when the load drops from full load to about 20% load, the frequency maintains a reasonable constant value. The frequency usually increases gradually when the load is less than 20%
