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.

摘要： This invention describes a high water content lipstick and its preparation. This formula includes 1-10 wt % emulsifiers, 1-30 wt % water phase and 69-98 wt % oil components phase. Pigments, pearl agents, water soluble active ingredients can be introduced when required. Polyglyceryl fatty ester, fatty ester and silicone derivative are combined as the mixed emulsifier to form a water-in-oil pre emulsion and then add this pre emulsion into other oil components. This preparing method is easy to handle and can increase the water content effectively. The samples produced according to this invention are very stable in storage and usage: no coarse surface or air bubbles phenomena appear. As this kind of formula comprises water, the cost may be lowered compared with normal anhydrous formulas, moreover, water soluble active ingredients are also possible to be added, which will give the consumer a totally new feeling. The invention can be widely applied in lip care products.
