New student members at Kawamura Laboratory,
regardless of their academic status, are encouraged to
participate in the Chopper Circuit Contest (CCC)
held every year during spring semester since 1999.
This enjoyable and instructive competition involves five
to ten participants and consists of an individual preparation
of a chopper circuit according to the guidelines
established by the organizing committee, composed by
some of the previous participants. A chopper is a
DC-DC converter, and in this contest it is to supply a
suitable clean power to a DC motor. Since 2002, when
FPGA-based control was introduced in the contest,
participants have to enable their circuits to operate in
both analog and digital modes.
After spending several hours to complete and test the circuit,
participants are requested to submit a report as well.
At the day of the contest, each person makes a short
presentation about their project including the
operation and efficiency evaluation. A judging
committee formed by Professor Kawamura and other
distinguished experts also rates the design/layout of
the circuit. General audience also contributes to the
selection process. The winner is decided according to
overall performance. The award ceremony takes place after
the final decision. The winner and other outstanding
participants receive the prizes directly from Professor
Kawamura as recognition for their efforts.
