摘要
提出了斩波式放大器的原理,并在时域及频域进行了理论分析。其结果表明,该放大器能实现对信号幅度的连续调节,在50Hz正弦波高频调制逆变电源上应用取得了非常好的稳压效果。
Explores the principles of the chopper amplifier and puts forth detailed theoretical analyses using time and frequency domains. Results indicate that the amplifier has the ability to continuously adjust signal amplitude.
