Abstract:

A circuit (C-C) is employed in a TWACS transponder (T) installed in an electric meter (M). The transponder generates inbound signals (IB) transmitted from the location of the electric meter to a central location (R). Firmware (F) within the transponder controls the flow of current for each pulse through the circuit by triggering a semi-conductor device such as a SCR (X) or TRIAC (X). The resulting current flow through the inductor for a subsequent pulse, regardless of the pulse's polarity, will be in the opposite direction to that of the previous pulse. The result is to maintain a constant level of magnetization of the inductor core which does not have to be overcome by energy in the subsequent pulse resulting in amplitude of all the pulses imposed on an AC waveform being substantially the same.
