This study suggests a combined source and load-side power management technique to control power in an isolated hybrid electric spring system. The literature reveals that the CL to NCL-ratio and the minimum voltage level selected for the NCL have a significant impact on the operational range of the ES. Either NCL must be sufficiently large or the minimum NCL voltage must be reduced in order to provide a wider operating range. Doing this, purposefully allows the NCL voltage profile to have declined. This research identifies this gap and suggests a multi-pronged control approach to try and enhance the voltage profile of the NCL. Additionally, the proposed control approach may aid in extending the ES's usable operating range. In this study, NSC was also discovered to be advantageous vs traditional back-to-back converters. The use of a coupling transformer on the shunt side is simply eliminated by the dc side voltage allotment mechanism in the NSC. To demonstrate the efficiency of the suggested control technique, the system is subjected to shunt power variation using torque variation. The entire project is modeled, simulated, and verified using the Matlab/Simulink platform and the OPAL-RT 5700.
