Benefits of technology

[0021]In brief, the present invention employs the feedback voltage to perform the dynamic regulation process, which generates and controls the driving voltage and the driving current, and then converts the input AC voltage into the output voltage for supplying the load. Thus, efficiency of power conversion is greatly increased and the effect of EMI is improved.

Problems solved by technology

However, one of the shortcomings in the prior arts is that the driving voltage for driving the switch unit and the driving current flowing through the switch unit are not appropriately adjusted according to the input voltage.
As a result, the power conversion is optimized for only one specific input voltage to reduce the switching loss and the conduction loss, and fails to covers the whole range of the input voltage.
It is difficult of further increasing efficiency of power conversion.
