In this paper we made our plan for High power L-C filter, then analyzed power factor and power efficiency. This study used voltage rectangular wave inverter circuit to the input power source for the purpose of making requtagular wave. If the filter is Butterworth, Chebyshev filter and so forth of R-L load, it is a power efficiency method that get rid of High frequency conponent. But this filter can't improve the power efficiency. Accordingly this study think two type filters. For one thing is (i) Improved Butterworth-Chebyshev filter, another is (ii) Improved constant K type filter. We improved those power factor and power efficency, then became graphic and examined them., 長崎大学工学部研究報告, 19(33), pp.29-34; 1989}, pages = {29--34}, title = {短形波電源における電力用フィルタによる力率及び効率の改善}, volume = {19}, year = {1989} }
