It also has a circuit in which a charger output circuit and an inverter input circuit are connected in parallel, and when the generator output wli is within a predetermined value, the phase relationship between the generator and the inverter is adjusted to generate power. The inverter adjusts the load so that the inverter shares the load, and when a predetermined value is about to be exceeded, only the excess amount is supplied from the inverter side.

れている。本実施例の動作原理を総合[のこ説明する。19 is an electromagnetic contactor on the generator power supply side, and 21 is an aS contactor on the inverter power supply side. 28.25 is a phase difference control reactor. The charger shown in this example is a fixed WIL51E for floating charging of ordinary stationary storage batteries.
In addition to the function as a constant voltage charger, the wl and Wt detected by the current transformer 13 also act as a constant current, and if the output current of the generator 8 tries to exceed a certain value, the output current of the charger is changed. The output of the current transformer 18 is automatically controlled so that the output current of the generator 3 does not exceed a certain value. In addition, the inverter 9 can take out an output having a certain phase relationship with the generator output voltage, and a phase adjuster 17
Therefore, if the current wl supplied from the generator to the load exceeds a certain value, the phase on the inverter side is advanced and the excess load DC current is supplied from the inverter to the load 11. The operating principle of this embodiment will be comprehensively explained.

係が成り立っている。In general, two power supplies are connected in series with the output sides of the reactors via a parallel supply type IIE source equipment, and the phase difference between the output currents Eo and [il is 61. θ2
Then [power PI supplied from source ■ and power source ■,
P2 is given by, similarly to equation (1). If we consider the power supplied to the load, there is P between P+, Pz, and Po.

する。The phase difference θr can take positive or negative values depending on the sign of at. That is, by adjusting the phase between the two power sources, it becomes possible to freely control the power supply state between the Wl source I and the Wl source ■. Next, examples of the present invention will be described.

舞は充WL器5を介して蓄電池7を充電し、発電機出力
は変流器13 により充11t流を調整して発電機出力
が一定となるように動作する。The engine 1 causes the generator 3 to generate electric power, thereby supplying electric power to the load 11. When the load 11 force is small, the battery 7 is charged via the charging WL device 5, and the generator output is adjusted by the current transformer 13 to keep the generator output constant.

入してインバータを時期させろ。Even if it is closed, the load 11 is immediately supplied (I'll ~ none), so adjust the inverter phase, and then turn on the electromagnetic contactor 21 to time the inverter.

t5ftをインバータ9より負荷に給電する。When the load increases and attempts to exceed the rating of the generator 8, the output of the current transformer 15 increases, and the phase adjuster 17 advances the output phase of the inverter (9) so that f exceeds the rating of the generator 3.
t5ft is supplied from the inverter 9 to the load.
従って発電機は定格運転を続けることができる。Therefore, the generator can continue its rated operation.
またインバータを運転するための出力は蓄11a7より

発電機出力に余裕が発生してから行われる。Further, the output for operating the inverter is supplied from the storage 11a7. Lighting up of the storage wIL pond 7 is performed after the load DC decreases and there is a surplus in the generator output.

Further, by carrying out the present invention, the generator will not be operated in an overload range, so that the generator itself can be operated economically at the most fuel-efficient location. Therefore, overall, it becomes possible to significantly reduce fuel consumption and enable energy-saving operation.
