Two-Stage Bi-Directional Single-Phase Converter with DC-Link Capacitor Reduction
It is well-known that single-phase ac-dc conversion requires a bulky dc-link capacitor for filtering the ripple power from the grid, thus leading a overall bulky converter size. Also, in order to interface a dc renewable energy system to a single-phase utility grid, bi-directional power flow control and dc-bus voltage regulation are major concerns....
