20080218103 | Load driving method - A load driving device controls two motors by PWM signals. When a standard duty ratio of the PWM signals is 50% and a level of a drive instruction is the standard duty ratio, the standard duty ratio are output to the respective motors to provide a reverse phase relationship that the PWM signal of the standard duty ratio does not overlap. A continuous off-period and the standard PWM signal output when the level of the drive instruction is lower than the standard, and the continuous on-period and the standard PWM signal output when the level of the drive instruction is higher than the standard are changed over at the ratios corresponding to the level of the drive instruction. | 09-11-2008 |
20100026355 | Load drive device and control system of the same - A load drive device for driving an inductive load by PWM controlling a switching element includes synchronization control unit, a synchronization signal input terminal, and a synchronization signal output terminal. The synchronization control unit outputs the PWM signal to the switching element. The synchronization control unit receives a synchronization signal through the input terminal from an exterior. The synchronization control unit outputs the synchronization signal through the output terminal to an exterior. When the synchronization control unit does not receive the synchronization signal, the synchronization control unit outputs the synchronization signal such that a first switching period of the PWM signal is prevented from overlapping with a second switching period of a PWM signal of an external device. When the synchronization control unit receives the synchronization signal, the synchronization control unit generates the PWM signal based on the synchronization signal. | 02-04-2010 |
