Abstract

In our original wire communication system that consists of low-power dc-dc converters, a converter in the powering terminal operates as not only power supply but also transmitter. Signal is transmitted by the use of output-voltage ripple. At transmission of message, the ripple is intentionally increased and modulated by the signal. Steady state and transient characteristics on FM (frequency modulation) by the way of varying the switching frequency are investigated. FSK (frequency-shift keying) is presented as an example of digital FM transmission and reception. In addition, we introduce a new electronic choke used in each terminal.
