ELIMINATION OF UNWANTED VOLTAGE DROPS ACROSS THE LINKS BETWEEN FOUR TERMINAL – PAIR COMPONENTS CONNECTED IN SERIES

• Abstract:

  Two possible methods of eliminating unwanted voltage drops in four terminal-pair bridge circuits are discussed, namely employment of combining networks and injection of compensation voltages. As an economical and practical way of producing these voltages, application of a slave digital synthesis (DSS) generator, directly synchronized with the source of the bridge supply voltage, is proposed. A possible design of such a generator, based on employment of a DSP evaluation board, is described.
