摘要
介绍了一种基于线性功放技术的DC/AC变换器。该DC/AC变换器主要由控制电路和线性功率放大电路构成。采用二阶有源滤波技术、稳幅技术及线性功放技术,实现输入500Hz方波信号到输出500Hz正弦波信号的转变。这种DC/AC变换器具有输出波形失真度小,输出幅度稳定性高等特点。
Based on linear power amplifier technology, a DC/AC converter was designed, which was comprised of control circuit and linear amplifier. In this converter, 2nd-order filter, amplitude stabilizer and linear power amplifier were adopted to realize conversion from 500 Hz square-wave input to 500 Hz sine-wave output. Test results show that the converter features small distortion in output waveform and high stability in output amplitude.
