20100080031 | POWER FREQUENCY CONVERTER - A current control circuit (active element) is provided that is connected between a rectifier of a DC power source and a smoothing capacitor in a power frequency converter and that controls a variation in the rectified current caused by a variation in the instantaneous power consumption of the load device. When the rectified current increases, the current control circuit limits the current to have a reference current value or lower and, when the rectified current decreases, the current control circuit increases the current to have a value close to the reference current to thereby suppress the rectified current from the rectifier to a substantially-constant value. This consequently mitigates the influence on the primary power source by the variation in the instantaneous power consumption of the load device, thus clearing the Load Demand Variation specification required for the power source to be used in an aircraft. | 04-01-2010 |
