Latest Patents

Chi-Hsien Ho holds a patent for a Multi-lamp driving system. This system includes a filter circuit, a switch circuit, a pulse width modulation (PWM) controller, a protection circuit, transformers, and an abnormity detection circuit. The primary windings of the transformers are connected to the switch circuit in parallel, while the high voltage terminals of the secondary windings are connected to lamps respectively. The abnormity detection circuit converts current signals flowing through the lamps into voltage signals, retrieving the highest and lowest voltage signals corresponding to the highest and lowest current signals respectively. It then determines if the difference between these voltage signals exceeds a predetermined value, generating a trigger signal if necessary. The protection circuit receives this trigger signal and controls the PWM controller to stop outputting PWM signals to the switch circuit.
