Abstract This article presents two power converters with controllers attached to the Free‐Piston Stirling Linear Generator (FPSLG) and energy storage system (ESS). The rectifier uses hysteresis‐SVPWM current regulation CB‐SPWM, while buck‐boost converter utilizes dual‐loop PI control method. battery receives from a linear‐generator converter. FPSE linear motors in FPSLG convert thermal electrical energy. A two‐level conversion technique using three‐phase AC signal DC DC‐DC has been devised reduce output oscillation as well stabilize generating system's power. Initially, FPSE's nonlinear model permanent magnet linear‐motor's mathematical were created followed by ESS mechanism simulation. simulation shows that approach can give stable PR controller replaces position loop improve frequency displacement tracing. design was simulated MATLAB topology's feasibility correctness confirmed. Comparative analysis that, H‐SVPWM's unity factor of stability controllability DC‐side voltage is better than CB‐SPWM approach.
