Abstract
The present invention includes a load-adaptive power generator including a feedback detecting module, a load determining module, a load driving module, and a control module. The feedback detecting module detects a load voltage of a load device, and converts the load voltage into a feedback voltage. The load determining module determines whether the feedback voltage is within a preset range for generating a periodical load driving signal. The load driving module has a plurality of driving units and at least one switch. The driving units drive the load device according to the load driving signal, and at least one driving unit receives the load driving signal through the switch. The control module turns on the switch when the frequency of the load driving signal is less than a frequency threshold. Accordingly, the load-adaptive power generator of the present invention can save energy.
