Performances of voltage boost and reduction of input power peaks in charge-pumped boost driver with EDLCs

The supply used in servo systems tends to have a high voltage in order to reduce loss and improve the response of motor drives. As a new boost driver, charge-pumped boost driver (CPBD) with electric double layer capacitors (EDLCs) was proposed. CPBD with EDLCs has advantages. The first advantage is that this driver can easily attain the stable boost voltage. The second advantage is that this driver can reduce input power peaks and therefore reduce the cost and the size of the supply facilities. This paper experimentally reports the sufficient performance of these advantages of CPBD with EDLCs, that is, the performances to boost the voltage and to reduce the input power peaks.
