Wire communication system utilizing ripple-modulated DC-DC converter as signal transmitter and power supply

A novel wire communication system which consists of low-power switched-mode DC-DC power converters is proposed in this paper. A converter acts as not only a power supply but also a transmitter. The main power unit in a conventional system can be removed and the system reliability is much increased, because converters construct a parallel-connected system with respect to DC power. Transmission of signals is performed by the use of output voltage ripple. At transmission, this ripple is increased intentionally and modulated. Both analog modulation and digital modulation are acceptable.
