Classification of control strategy of parallel inverter The parallel inverter control mechanism aims at achieving regulated voltage and power besides accurate power share which depends on active load/current sharing. The control strategies for the parallel inverter control are aforementioned in the literature as active load sharing techniques.

In scenarios requiring higher capacity, connecting inverters in parallel can be a solution. When power inverters are connected in parallel, the output capacity is essentially increased, allowing for a greater AC load than a single inverter could handle alone. However, for a successful parallel connection, the inverters must be "parallel ...
