Abstract
A voltage adaptable driving signal converter is disclosed, including a rectifying device, a pre-stage energy storing device, a DC-DC conversion device, a post-stage energy storing device, a control conversion device and a switch control device. The rectifying device, the pre-stage energy storing device, the DC-DC conversion device and the post-stage energy storing device are sequentially connected. The pre-stage energy storing device is coupled to a positive electrode of a power supply or to a grounding electrode. The post-stage energy storing device is coupled to and adapted to supply electrical power to a load to be driven. The control conversion device is coupled to the control line and the switch control device respectively. The switch control device is coupled to the post-stage energy storing device and the load respectively. With the above voltage adaptable driving signal, a low-voltage load can be driven by a high-voltage control signal, and a high-voltage load can be driven by a low-voltage control signal, or a load which is not convenient to be made into a high-voltage load can incorporate the voltage adaptable driving signal converter to become a high-voltage load, to achieve the matching between the switch control signal and the load.
