In this paper, a novel active boost converter for the SR drive is proposed. An active capacitor circuit is added in the front-end. Based on this active capacitor network, when the boost switch turns off, this network seems as a passive capacitor network. And the voltage of boost capacitor can keep balance with the DC-link voltage automatically. In the capacitor network, the discharging voltage is...
In this paper, a novel passive boost converter for SR drive with high demagnetization voltage is proposed. A simple passive circuit is added in the front-end of conventional asymmetric converter, which consists of three diodes and one capacitor. Based on this passive network, the two capacitors can be connected in series or parallel in different operation status. So the terminal voltage of the converter...
