| 20110291573 | RESONANT POWER SUPPLY FOR LIGHT-EMITTING DEVICES - A resonant power supply for light-emitting devices comprises an inverter including two DC input terminals and two AC output terminals, a resonant circuit connected in series to at least one of the two AC output terminals, and an LED circuit connected in series to the resonant circuit. The inverter is configured to convert a direct current from the two DC input terminals into an alternating current through the two AC output terminals, and the LED circuit emits lights as the alternating current is applied. | 12-01-2011 |
| 20110241588 | SYSTEM AND METHOD FOR CONTROLLING SENSORLESS MOTOR - A system and a method for controlling a sensorless motor are disclosed, where the system includes a motor driver and a zero crossing detector. The motor driver can drive the sensorless motor. The zero crossing detector can detect a zero-crossing point when the voltage of one motor coil of the sensorless motor is in a blanking period. | 10-06-2011 |
| 20110074322 | APPARATUS AND METHOD FOR DETECTING LOCK ERROR IN SENSORLESS MOTOR - An apparatus and a method for detecting a lock error in a sensorless motor are disclosed, where the apparatus includes a multiplexer, a negative booster, a comparator and a timer. The multiplexer can receive a coil voltage from the sensorless motor. The negative booster can receive a neutralizing voltage from the sensorless motor and drop the neutralizing voltage. The comparator can compare the coil voltage with the dropped neutralizing voltage for outputting a zero-crossing signal. The timer can count time duration during the zero-crossing signal maintained at the a logic level and determine the lock error in the sensorless motor when the time duration exceeds a predetermined period. | 03-31-2011 |
| 20110062907 | APPARATUS AND METHOD FOR DRIVING SENSORLESS MOTOR - An apparatus and a method for driving a sensorless motor are described and shown in the specification and drawings, where the method includes steps as follows. First, a control signal is acquired, where the control signal has information of a predetermined rotational speed. Next, energy is supplied and progressively increased to the sensorless motor, so as to rotate a rotor of the sensorless motor. Then, a position of the rotor is detected. Finally, the energy is gradually regulated so that the sensorless motor is maintained at the predetermined rotational speed. | 03-17-2011 |
| 20100052140 | PACKAGE STRUCTURE - In the specification and drawing a package structure is described and shown with a first die including a high side driver, a second die including a low side driver and at least one conducting wire, wherein the conducting wire is coupled with the first die and the second die. | 03-04-2010 |
| 20090256619 | HIGH-SIDE DRIVER - A high-side driving circuit is provided, where Q terminal and | 10-15-2009 |
| 20090250727 | SUPER JUNCTION SEMICONDUCTOR DEVICE - In the specification and drawing a super junction semiconductor device is disclosed. The super junction semiconductor device comprises a P-type layer, a N | 10-08-2009 |
