器３にて該交流電圧を直流電圧に変換している。Conventionally, the electric circuit of an automatic military alternator for boat fishing has been constructed as shown in FIG. That is, the alternator is driven by the engine, and by passing a current through the field coil 1, an alternating current voltage is generated in the stator coil 2, and the alternating current voltage is converted into a direct current voltage by the rectifier 3.

出力電力は減少する、という−船釣な特性がある。FIG. 4 is a diagram showing general characteristics of an alternator. In other words, the output voltage droop and power measured against the output current when the field current of the alternator is constant are measured by changing the rotation speed.The horizontal axis represents the output current, and the vertical axis represents the output voltage and output power. FIG. The output voltage increases in proportion to the rotation speed. Further, as shown for the rotational speed Nd, the output voltage (indicated by point A in the figure) at the maximum power Wd is about 2/2 of the no-load output voltage (indicated by point B in the figure). In other words, the output voltage of the alternator increases in proportion to the rotation speed, and the output power is approximately 1 of the no-load output voltage.
The output power increases until the output current reaches /2, and the output power decreases for output current exceeding that value.

以下の状態で使用されている欠点がある。As is clear from Figure 6, in the conventional device, the number of rotations that can be used at the maximum output power that the alternator can output is only one point (Nb), and most alternators are used at less than the maximum output power. There are drawbacks.

きにＤＣ−ＤＣコンバータｉｔに指示を送る。A voltage of approximately 172 as a no-load voltage corresponding to the rotation speed of the alternator 6 is set in the rotation-voltage conversion circuit 13 based on the frequency of the half-wave rectified voltage 17 output from the stator coil 2. DC-DC converter output VII17
is controlled to be vl when there is no instruction from the voltage comparison circuit. The voltage comparison circuit 12 compares the output voltage of the rotation-voltage conversion circuit 13 with the output voltage v4 of the alternator 6. When the output voltage of the rotation-voltage conversion circuit 13 is large, an instruction is sent to the DC-DC converter IT.
