In this study, a new switched‐mode bridgeless converter operating in the discontinuous conduction mode is presented along with an input resistance control scheme. Through feedback control, the converter‐battery circuitry synthesises variable line resistor with regenerative capability is intended for large‐scale electromagnetic‐based energy harvesting systems. For instance, the circuit can operate as a vehicular regenerative damper through converting vibration energy into battery charge. Analysis of the power converter in various switching modes is presented along with implementation of a control method for synthesising a desired input resistance. Experimental and simulation results are presented that highlight operations and power efficiencies of the proposed power converter along with its control scheme.
