Tunable switch-mode emulated inductive elements for enhanced power converter miniaturization

This work presents the emulation of tunable switch-mode inductive elements for power converters applications. Such elements are based on the concept of ideal loss-free realization by means of switch-mode circuits. A gyrator-based approach for synthesizing inductors is demonstrated. The value of the emulated inductance could be tuned by using appropriate control which would help to alleviate common undesirable properties of conventional passive implementations such as tolerance and value change over temperature and time. This approach enables monolithic circuits composed of semiconductor devices and small inductors/capacitors to be used to emulate large reactive components as a step forward for enhanced power converter miniaturization and integration.
