The thermodielectric converter, a device employing a ferroelectric material as the active element in converting thermal to electrical energy, is analyzed. The efficiency and power‐handling capacity are calculated for operation of a ferroelectric material in the induced‐ferroelectric region on the basis of an idealization of the polarization (P‐E) characteristics. The idealization includes the induced‐ferroelectric transition but excludes hysteresis and other nonlinear effects. For a barium titanate‐like material, the following values are obtained: A maximum theoretical efficiency of about 0.5% in an ideal temperature cycle of Carnot efficiency 7.1%; and a power‐handling capacity of roughly 32 w/lb per temperature cycle per sec.
