In this paper, a phase-decoupled flux-reversal linear generator for low-speed reciprocating power generation is presented. The proposed linear generator adopts a short-primary and long-secondary structure. The primary consists of six identical C-cored modules housing both permanent magnets (PMs) and the armature winding. The secondary is passive and stationary. By using the independent C-cored modules and flux-reversal configuration, six phases are magnetically decoupled from each other. In order to maximize the delivered power from the linear generator to the load, an impedance matching strategy is applied to suppress the circuit reactance. Both simulation and experimentation are carried out to verify the effectiveness of the proposed linear generator and the impedance matching strategy.
