Study of parallel operation single phase H-bridge CSI and H-bridge VSI

International Journal of Power Electronics and Drive Systems (IJPEDS)
In some applications, parallel operation of some single-phase inverters with different characteristics is a necessity, such as in a photovoltaic power conversion system. Each power inverter with its power source works, delivering power to a common load which cannot be supplied by a single power inverter.
