Voltage supply is24V.This product is a push-pull power amplifier module. 供电电源24V,本产品是推挽型功率放大模块。
Now, you might be thinking, how can a push-pull amplifier be class A? 现在,你可能会想,怎么能推挽放大器是A类?
A single-ended class A amplifier output transformer is huge compared to a push-pull class A amplifier of the same power level. 一个单端A类放大器的输出变压器是巨大相比,推挽A级放大器相同的功率水平。
Second, a push-pull class A amplifier output stage will have inherent rejection of power supply ripple and noise. 第二,推挽A级放大器输出阶段将拥有固有拒绝电源纹波和噪声。
When designing output stage, in order to enhance the efficiency, it uses the push-pull common source stage amplifier as the output stage, the output voltage swing basically reached rail-to-rail. 在输出级设计时,为了提高效率,采用了推挽共源级放大器作为输出级,输出电压摆幅基本上达到了轨至轨;
Grounding on above theory, the ZVS resonant of soft switch full-bridges circuit, and class-E amplifier, and push-pull class-E amplifier are analyzed respectively in theory. 基于以上理论,分别选择了ZVS谐振型全桥串联逆变器、E类放大器以及推挽式E类放大器进行详细的理论分析,仿真比较以及小功率实验对照。
Experiment result proved, relative to complicated structure and high request for laying wiring of ZVS series resonant full-bridges, push-pull class-E amplifier is expected more suited for high frequency high-power output ability relatively, which is suitable for popularizing. 实验证明,相对于结构复杂,布线要求较高的全桥串联谐振逆变器,推挽式双E类放大器具有更高频率和较大功率的输出能力,适于推广一。
