Control techniques for dc/dc converters
All dc/dc converters are used to convert one dc voltage to another. These converters are used in industry as well as in research. One of the main limitations of these converters is unregulated supply of voltage and current. To overcome these problems, various control techniques are used in combination with the converters. This paper summarizes few of control techniques including voltage mode control (VMC), current-mode control (CMC), proportional-integral-derivative controller (PID), sliding mode (SM) control, and fuzzy logic control. The paper also pays attention on the advantages and disadvantages of these techniques with basic operating principle. For more information, see “Control techniques for dc/dc converters.”
EV charging stations
Fuji Electric Corp. of America announced that it has partnered with Union Bank and Marlin Leasing to offer its customers convenient financing programs on its dc quick-charging stations for electric vehicles. The program offers zero-down, zero-interest financing in an effort to offset the cost of equipment and encourage small businesses to install charging stations at their sites.
The company believes that the development of charging infrastructure in the U.S., particularly publicly available quick charging, is a critical factor in the mass adoption of EVs. Drivers need reassurance that they will be able to access charging stations while on the road, and this financing program gives businesses the assistance they need to make a business case for the installation of these quick-charging stations.
Fuji Electric’s UL-Certified 25-kW dc quick-charging station provides a complete charge to EVs in under an hour, making it suited for commercial applications such as hotels, restaurants, retail stores, and public highways/interstates.
More than 400 units are deployed worldwide. The global manufacturer entered the U.S. market in March 2012, and immediately recognized the hesitation among businesses to invest in the technology. The financing program is currently available to U.S. customers, and is designed to offer quick turnaround time on application reviews to avoid project delays.
