    • A power amplifier circuit that has an inductor and capacitor connected to one end of the output winding of an RF transformer. The other end of the output winding is connected to a resistor that in turn is connected to ground. The transformer has two primary windings. Both primary windings have one end connected to a variable DC voltage supply. The other end of each primary winding is attached to a switch, such as a MOSFET. All three windings are wound around a core. Current flowing from the DC voltage supply to the switches causes a magnetic flux in the core. A voltage is generated on the secondary winding resistor. This voltage is fed back to the switches, controlling on and off timing, hi this way the need to measure and record natural frequency is eliminated.
    • 功率放大器电路,其具有连接到RF变压器的输出绕组的一端的电感器和电容器。 输出绕组的另一端连接到电阻器,该电阻器又连接到地。 变压器有两个初级绕组。 两个初级绕组的一端连接到可变直流电压源。 每个初级绕组的另一端连接到诸如MOSFET的开关。 所有三个绕组缠绕在一个芯上。 从直流电源流向开关的电流导致磁芯中的磁通量。 在次级绕组电阻上产生电压。 该电压被反馈到开关,控制开和关定时。这样,消除了测量和记录固有频率的需要。
