The effect of the type of power cycle upon the amount of output electrical work for a pyroelectric converter has been measured. Output electrical energy densities are reported for ceramic lead zirconate modified with Sn/sup 4 +/ and Ti/sup 4 +/ in the execution of a variety of thermal-electrical cycles. The effect upon the energy density due to changes in the voltage cycle limits and changes in the load resistance were also studied. A conversion cycle which is an electric analog of the Ericsson cycle is shown to yield the largest output energy density (100 mJ/cm/sup 3/ for a 12.6 K temperature excursion and a 28-kV/cm electric field excursion).
