Patent JP-2012100500-A (JP)
Title: Complex power supply system
Inventor: MATSUO HIROYUKI
IPC: H02P27/06
Filed: 2010-11-05
Abstract: PROBLEM TO BE SOLVED: To resolve a problem that, in a conventional circuit, a step-down ratio and a step-up ratio of a step-up/step-down chopper become large when an AC input voltage is high, which causes that a generated loss is biased to a specific semiconductor element, and as a result, the element and a cooling device become large in size and high in cost.SOLUTION: When an AC power supply voltage is high (e.g. 400 V), a regenerative power from an electric motor is discharged once to a DC input of a CVCF (Constant-Voltage Constant-Frequency) inverter by a second step-up/step-down chopper, and the discharged power is charged in power storage means by a first step-up/step-down chopper. In addition, at the time of interruption of the AC power supply or voltage reduction, discharge from the power storage means to the DC input of the CVCF inverter is performed by the first step-up/step-down chopper, and the DC power is discharged to a DC intermediate capacitor by the second step-up/step-down chopper.

Abstract: PROBLEM TO BE SOLVED: To provide a highly-versatile driving device capable of activating various sensorless fan motors.SOLUTION: A BEMF (Back ElectroMotive Force) detection circuit 10 generates a rotation detection signal S3 indicating a result obtained by comparing back electromotive forces V-Vgenerated at respective one ends of a plurality of coils with a midpoint voltage V, respectively. A rotor position detection circuit 38 generates a rotor position detection signal S10 indicating a position of a stopped rotor. An internal activation synchronization signal generator 40 generates a forced synchronization signal SYNC2 having a predetermined frequency. A driving signal composition circuit 14 generates a driving control signal S4 depending on the rotor position detection signal S10 when activation of a fan motor 6 is instructed. As a result, (1) when the back electromotive force is generated, sensorless driving based on the rotation detection signal S3 is started, and (2) when no back electromotive force is generated, the driving control signal S4 is generated based on the forced synchronization signal SYNC2, and thereafter, when the back electromotive force is generated, the sensorless driving based on the rotation detection signal S3 is started.
