    摘要： A power saving vacuuming pump system is based on complete-bearing-sealing and dry-large-pressure-difference root vacuuming root pumps includes an input valve at an input end of a vacuum space for receiving gas mixture of saturation water vapor and non-condensed air from a condenser of a power plant; a first root vacuum pump connected to the input valve for receiving gas mixture from the input valve and then compressing the gas mixture; a second root vacuum pump connected to the first root vacuum pump for receiving gas mixture from the first root vacuum pump and then compressing the gas mixture. Inner connection walls between the vacuum chamber and the two bearing rooms are installed respective bearings which are installed to be around the driving shaft, and thus all the vacuum chamber and the two bearing rooms are tightly sealed. The vacuum chamber is completely dried so as to prevent from internal emulsion.

    摘要： Multilevel converters and space vector modulation operating methods are presented in which fewer than all possible switching states are employed for space vector modulation of rectifier and inverter circuits to promote common mode voltage contribution cancellation or reduction therebetween and by using subsets of possible space vector modulation switching states associated with minimal positive or negative common mode voltages and in some cases using virtual vectors which have zero common mode voltages to eliminate the 3rd order harmonic components in common mode voltage as well as to reduce common mode voltage affects associated with multilevel inverter stages.

    摘要： A system comprising low cost topology for power converter systems is provided. The system takes advantage of the voltage-boost characteristic of a current source inverter (CSI) and utilizes a PWM CSI as a grid-side converter for power generation systems. Moreover, the generator-side converter employs low-cost devices, such as, but not limited to diode bridge, thyristor bridge, and/or a combination of diodes and thyristors, and accordingly simplifies generator-side converter and control. Further, the system provides a wider range of operation than traditional voltage source converter based topologies that utilize a voltage source inverter (VSI) as the grid-side convertor along with a diode rectifier as the generator-side converter.
