<p>PURPOSE:To provide an inverter controlled generator in which erroneous func tion due to differential rising characteristics, caused by the differential characteristics of elements constituting positive and negative power supply circuits, can be prevented immediately after start of engine. CONSTITUTION:Frequency of output L from a sub-output winding 2 is detected by a number of revolution detecting circuit 8 for generator as the number of revolution of an engine and when a set value is exceeded, the detecting circuit 8 outputs a High level. On the other hand, voltage at an input terminal G of a low voltage circuit 5a is detected by a control power supply voltage detecting circuit 71 and when a set value is exceeded, the detecting circuit 71 outputs a High level. When both outputs go High, an AND circuit 703 outputs High level and a PWM signal is fed to an inverter circuit 9.</p> |
