車両に搭載し使用される電子装置等の電源装置に要求さ
れる性能は、一般に入力電圧の変動が±５０％に対して
、出力変動は数パーセントで、入力電圧と直流的に絶縁
された数種類の直流または交流出力である。The performance required of power supply devices such as electronic devices installed and used in vehicles is generally that the input voltage fluctuation is ±50%, but the output fluctuation is a few percent, and there are several types that are DC isolated from the input voltage. DC or AC output.
従来この種の電源装置としては、トランジスタを使用し
た直列形定電圧装置により一定電圧とし、その電圧によ
りインバータ装置を駆動し交流とし、変圧器で絶縁して
出力とするのが一般的であった。Conventionally, this type of power supply device typically uses a series type voltage regulator using transistors to maintain a constant voltage, and uses that voltage to drive an inverter device to generate alternating current, which is then isolated by a transformer and output. .
ところが直列形定電圧装置は、入力電圧変動の最低値か
ら最高値までの電圧差を直列に挿入されたトランジスタ
に熱として消費させるため、効率が悪く、発熱が大きい
ため装置として大型になる欠点を有していた。However, series type voltage regulators have the disadvantage that they are inefficient and generate large amounts of heat because the voltage difference between the lowest and highest input voltage fluctuations is consumed as heat by the transistors inserted in series. had.
この改良として前記直列トランジスタをスイッチングさ

欠点があった。As an improvement to this, a power supply device has been put into practical use in which the series transistors are switched and the output is smoothed by a filter, which is replaced with a so-called chopper-type voltage regulator, but the control circuit of the chopper device is complicated and expensive. There were drawbacks.
本考案はチョッパ装置の制御回路に磁気増幅器を使用し

4, and is connected so that it is compared with a set value based on the Zener voltage of the Zener diode ZD, and a control current proportional to the difference flows.
一方、交流巻線ＮＬＩ、ＮＬ２は前記巻線Ｎ３．Ｎ’３

が設定値に制御される。As a result, the time during which the transistor TR of the boost chopper converter 2 is also conductive becomes shorter, the stored energy of the reactor L decreases, and the voltage of the capacitor C also decreases, resulting in a decrease in the winding N3 of the self-oscillating inverter 3. The voltage of N'3 is controlled to a set value.
逆に自己発振形インバータ３の出力電圧が設定値より減
少すると、前記とは逆の動作を行ない、常に設定値に制
御されることは容易に判断できる。On the other hand, when the output voltage of the self-oscillating inverter 3 decreases below the set value, it can be easily determined that the inverse operation to that described above is performed and the output voltage is always controlled to the set value.
