20160105172 | ACTIVE DIODE HAVING IMPROVED TRANSISTOR TURN-OFF CONTROL METHOD - An active diode that features improved control of transistor turn-off is provided. Such an active diode may include a comparator to compare voltages between opposite ends of a parasitic diode, and a gate driver to control a gate terminal of the transistor according to the comparison result of the comparator. Furthermore, the active diode may further include an off-timing controller to control the transistor to be turned off at a point in time when voltages of the opposite ends of the parasitic diode turn positive. Thus, the active diode may be turned off when required. | 04-14-2016 |
20160072498 | GATE DRIVER FOR ISOLATED INPUT SWITCHING ELEMENT - A gate driver driving a switching device is disclosed. The gate driver includes a capacitor which is coupled to the input of the switching device. The gate drive power consumption is reduced by this additional capacitor. | 03-10-2016 |
20160036436 | ACTIVE DIODE DRIVER - An active diode driver for operating a switch of an active rectifier using an active diode is provided. The active diode driver may first control a soft turn-on of the switch and secondly control a hard turn-on of the switch, thereby making it possible for the switch to be softly turned-on. | 02-04-2016 |
