20130127382 | POWER TRANSDUCER - The performance of a power transducer is improved while efficiently using a power semiconductor also by managing the permissible duty factor of the power semiconductor in the regenerative braking circuit provided in the power transducer. The user is allowed to set, through an operation panel provided on the power transducer, the resistance value of the regenerative braking resistor for thermally consuming the rotational energy generated during motor deceleration. The power transducer performs the steps of: calculating the current which flows in the regenerative braking circuit from the resistance value setting; obtaining the generation loss of the power semiconductor in the regenerative braking circuit with the calculated current value; and determining the permissible duty factor of the power semiconductor from the obtained generation loss. | 2013-05-23 |
20130127383 | INVERTER APPARATUS AND INVERTER CONTROL METHOD - An inverter apparatus basically includes an inverter, a rotational speed detecting component and a control component. The inverter includes a plurality of pairs of switching elements. The control component controls an on-off status of the switching elements to convert a direct current from a direct current power source into alternating current by alternately executing first and second controls when a rotational speed of a motor connected to the switching elements is larger than a prescribed rotational speed. The first control turns on the switching elements that are directly connected to a positive electrode of the power source, and turns off the switching elements that are directly connected to a negative electrode of the power source. The second control turns on the switching elements that are directly connected to the negative electrode and turns off the switching elements that are directly connected to the positive electrode. | 2013-05-23 |
