Abstract

The invention discloses a load driving device, which comprises a DC high voltage generation line, a switching line, a transformer and a control line, wherein the DC high voltage generation line is used for selectively receiving one of a first AC input voltage and a second AC input voltage which are different, processing the received AC input voltages to acquire and provide DC voltages, and after the first or the second AC input voltage is processed, the acquired DC high voltage is the same substantially or approximately; the switching line is used for responding to two complementary pulse width modulation signals and selectively outputting a DC high voltage and a grounding potential to provide an AC signal; the primary side of the transformer receives the AC signal from the switching line, and the secondary side responds to the AC signal and provides a driving signal to drive a light emitting load; and the control line is used for generating two complementary pulse width modulation signals to control switching of the switching line.

Description

technical field [0001] The present invention relates to load driving technology, and in particular to a load driving device with wide voltage input and built on a transformer with a single specification. Background technique [0002] Generally, transformers with different specifications (for example, transformers with different coil ratios) must be used in the 110ACV (alternating current voltage) load drive device / system and the 220ACV load drive device / system. In this way, the transformers in the 110ACV load drive device / system and the 220ACV load drive device / system must be purchased separately (that is, two different materials need to be purchased), which will not only cause purchase costs The improvement, but also cause the inconvenience of material inventory management. Contents of the invention [0003] In view of this, the present invention provides a load driving device with a wide voltage input under a single-size transformer, so as to effectively solve the probl...
