<p>PURPOSE:To ensure adequate operation of a load by comprising a generator to be driven by an engine to output power of the predetermined voltage, a main power outputting means for outputting in direct an output of generator and a subpower outputting means for outputting an output of generator through voltage stabilization control. CONSTITUTION:A portable engine generator 1 supplies in direct an output of a 3-phase synchronous generator 5 to the main power supply output terminal 37. Moreover, an output of generator 5 is controlled to the predetermined voltage by LRT and is then supplied to the subpower supply output terminal 39. Accordingly, the power supply voltage to be supplied to the subpower supply output terminal 39 becomes a constant voltage almost not affected by variation of output voltage of the 3-phase synchronous generator 5. Thereby, the range for adequate operation of the electromagnetic switches 129, 131 for making ON and OFF the current to motor can be widened by connecting a motor control panel 100 to the portable engine generator 1.</p> |
