<p>PURPOSE:To suppress the wiring inductance to a small value by containing a filter condenser in the same box as a controller. CONSTITUTION:Filter condensers 21 are respectively contained in the same box as inverters 22 of respective phases. Since the wiring length from a filter condenser to the inverter can be shortened in this manner, the wiring inductance can be suppressed to a small value, and an overvoltage which is generated when a gate turn-off thyristor is OFF can be absorbed by a snubber condenser which has smaller capacity.</p> |
