Boost motor driver with electric double layer capacitor
Apr. 2008 〜
Electric double layer capacitor (EDLC) have considerable capacity of energy
storage and can output the energy in low output-impedance. However, its
considerably low rated-voltage prevents itself from practical use. The
proposed motor driver has the topology that EDLCs are connected with the
DC link in series. The topology enables the driver to boost its output
voltage. On the other hand, this topology is suitable tor EDLC because
it requires low rated-voltage.
Moreover, by using EDLCs, the driver can store regenerative energy at braking of motor. In contrast, conventional drivers dissipate regenerative energy, which considerably decreases the efficiency. Consequently, the proposed driver can drive a motor efficiently.
We shall improve the driver so that it becomes more compact and efficient.
