Abstract
In this paper, we used class D amplification circuit to improve the decline of error rate caused by low impedance in the Power Line Communication. We manufactured voltage drive circuit and current drive circuit that are driven circuit of power line modem on the present and made a comparison experiment with drivel circuit that uses class D amplifier proposed in this paper. As a result of Experiment, We showed that it has great superiority over other existing drive circuits at rapid impedance change in power line channel.
