Regenerative thermoacoustic energy converter (TAEC) powered by a radiant or other heat source (6) at which the regenerator (4) and low temperature heat exchanger assembly (5) is build up, as short, separated ring shaped sections connected acoustic and thermal in parallel over the longitudinal length of the radiant heat source. Each section is provided with a dedicated acoustic timing circuit (9) to set the acoustic regenerator impedance in each separate section to the appropriate high absolute value and near zero phase difference between pressure and velocity amplitude. Because of this impedance setting per section is hardly dependent of the number of sections or longitudinal position of each section inside the acoustic resonator, much higher thermal and acoustic power levels are feasible at given system dimensions.
