摘要： When the power source voltage is charged to a capacitor between the source side of a MOSFET and a saturation reactor at the time of starting, the gate voltage of the MOSFET is caused to rise. When this charging voltage or the gate voltage exceeds the threshold voltage, the MOSFET is energized. The energization of this MOSFET induces a voltage in the tertiary self-excited oscillation winding through the primary winding, and a part of the induced voltage is applied to the gate of the MOSFET while some other part is applied to the reactor. This causes the magnetic flux of the saturation reactor to be set to the direction opposite that which had been set before. When the product of the voltages applied to the saturation reactor has reached the level for the allowable saturation magnetic flux density the saturation reactor is saturated and the gate voltage is discharged to turn off the MOSFET. When the MOSFET is energized once, the setting and resetting of the saturation reactor is repeated alternately due to the actions of the primary winding and the tertiary self-excited winding to enter the state of stable operation.

摘要翻译： 当电源电压在MOSFET的源极侧与饱和电抗器之间的电容器充电时，MOSFET的栅极电压升高。 当该充电电压或栅极电压超过阈值电压时，MOSFET通电。 该MOSFET的通电在通过初级绕组的三次自激振荡绕组中产生电压，并且将一部分感应电压施加到MOSFET的栅极，而另一些部分被施加到反应器。 这使得饱和电抗器的磁通量被设定为与之前设置的方向相反的方向。 当施加到饱和电抗器的电压的乘积达到容许饱和磁通密度的水平时，饱和电抗器饱和，并且栅极电压被放电以关断MOSFET。 当MOSFET通电一次时，由于初级绕组和三次自励绕组的动作进入稳定运行状态，饱和电抗器的设定和复位交替重复。

摘要： There is provided a digital controller which can generate no oscillation even if sensing a load side and enables control of supplying a desired voltage to the load. In an power amplifier which supplies an output voltage vo to the load connected via a load connecting line, a load voltage vL and the output voltage vo are periodically sampled to calculate a manipulating variable ξ1 from the output voltage vo, the load voltage vL and an arbitrary target value r. Based on the manipulating variable ξ1 calculated, a control signal is output to the power amplifier. As a result, when connecting an LC filter with a load device 9 of the power amplifier intended for a control target and besides the load connecting line is long, a robust digital controller without generating oscillation even if sensing the load side is performed can be realized.
