Abstract :
Multi-level two-quadrant boost choppers are proposed for superconducting magnetic energy storage (SMES) and other applications with inductive energy storage such as magnetic resonance imaging (MRI) and switched reluctance motor drives. The advantages of multi-level power conversion includes lower current ripple, lower switching loss and better voltage sharing, as illustrated with a 3-level power converter as an example. Its operation principle and PWM strategies are investigated, and a small signal model is developed for control design. Simulation results are used to verify the analysis
