Abstract:
An apparatus having a generator driven by an engine and an inverter unit comprising a converter for converting an alternating current of the output of the generator into a direct current and an inverter circuit for converting the direct current into an alternating current of a predetermined frequency, the inverter unit connected at its output to a power supply system, comprising:a controlling power supply for controlling the engine and the inverter unit; a first power supply link for rectifying and supplying to the controlling power supply a level of electricity received from the power supply system while the engine remains not actuated; and a second power supply link for supplying the controlling power supply with a level of electricity received from the input of the inverter circuit when the engine has been started, wherein the switching from the first power supply link to the second power supply link is automatically carried out when the voltage at the input of the inverter circuit is increased to a target level.
