Engine speed controlled generator set having an inverter and direct current output smoothing capacitor

A generator set having a converter composed of semiconductor rectifying devices for rectifying the power output of a magnetic generator, a capacitor smoothing means for smoothing a direct current output of the converter, and an inverter for converting an output of the capacitor smoothing means into an alternating current form at a particular frequency, comprising:

• a semiconductor rectifying device driving means for controlling the conduction of the semiconductor rectifying devices to maintain the smoothed voltage output of the capacitor smoothing means at a target voltage level;
• an average calculating means for calculating an average of the smoothed voltage output;
• and
• a target voltage level adjusting means for increasing the target voltage level to raise the average when the average is smaller than the target voltage level by a specific amount.
