The load dump protector determines a turnoff timing of the switching element as the low-side rectifying element for the at least one of the plural-phase stator windings after the output voltage, which exceeded the first threshold voltage once, falls below a second threshold voltage. The second threshold voltage is set to be lower than the first threshold voltage. The load dump protector turns off, at the determined turnoff timing, the switching element as the low-side rectifying element for the at least one of the at least two-phase stator windings. | 2012-01-05 |
| 20120001599 | Power Supply Circuit Capable of Handling Direct Current and Alternating Current and Power Supply Control Method - According to one embodiment, a power supply circuit includes an input terminal, a rectifier circuit, a power factor improvement circuit, a DC/DC converter, and a control module. The DC/DC converter converts the level of a DC voltage output from the power factor improvement circuit. The control module determines on the basis of the output voltage of the rectifier circuit whether an input power supply supplied to the input terminal is AC or DC. The control module generates a DC power supply by use of the power factor improvement circuit and DC/DC converter when the input power supply is AC and generates a DC power supply by controlling the operation of the power factor improvement circuit and DC/DC converter according to the voltage of input DC power supply when the input power supply is DC. | 2012-01-05 |
| 20120001600 | CONTROL CIRCUIT OF INTERLEAVED PFC POWER CONVERTER - A control circuit of an interleaved PFC power converter according to the present invention comprises a master switching control circuit, a slave switching control circuit, and a slave reference signal generator. The master switching control circuit generates a control signal and a first switching signal in response to an input voltage and a feedback signal. The first switching signal is utilized to control a first switch of the PFC power converter. The slave reference signal generator generates a slave control signal in response to a load condition of the PFC power converter and the control signal. The slave switching control circuit generates a second switching signal in response to the slave control signal. The slave control signal is utilized to control a second switch of the PFC power converter. The slave reference signal generator adjusts the control signal in response to the load condition for generating the slave control signal correspondingly. The slave control signal drives the slave switching control circuit to adjust the switching frequency of the second switch for reducing the switching loss. | 2012-01-05 |
