Abstract

Recently, systems become complicated for aiming at their high performance in various fields. With increasing of complexity of systems, quantity of their wiring becomes enormous. We have been developed researches for reducing quantity of wiring by using unique spread spectrum (SS) technique with only gate switching. The SS method can be applied directly in power electronics systems. In this paper, we show the proposed SS method which is non-interference between channels. Next, we compare the error rate of proposed SS method to that of usual SS method using M-sequence code. Based on these fundamentals, we construct multiple power transmission system of 7 channels in which 7 EX-NOR gates and 7 analogue gates are used for modulation and demodulation respectively. In this system power with informations are transmitted with no interferences between channels, and it is successful to regenerate power for controlling each load.
