摘要： A new multi-function shunt active filter has been successfully implemented. The proposed decoupler and cascade controller provide a simple solution to power factor correction, reduction of harmonics loads and load balancing. The mathematical burden of resolving the load current to fundamental and harmonics is not required. The decoupler and controller can easily be implemented using low-cost analogue devices.

摘要： The present invention relates a system for compensating for a voltage dip and undervoltage containing a primary side and secondary side transformer, a voltage dip/swell detector, and a level detector/switch selector device, wherein the secondary side of the transformer possesses a minimally sufficient number of taps to allow the system to be modified to meet supply voltage dips. The system, in particular, allows for long term compensation of voltage dips and quick adjustment of load voltage, usually within one cycle. Methods of using the present invention are also presented.
