Design of the Two Parallel Inverter Modules by Circular Chain Control Technique

This paper presents the design technique of two parallel inverters. The parallel inverter can be shared the power with efficiently. The proposed technique is presented using the circular chain control (3C) to manage two parallel inverters operation. The inverter control is used by dsPIC 30F4011. The two set of 50 watt inverter are prototyped. The flowchart of operating condition is proposed to maintain the power sharing and the system efficiency. The simulated result using Simulink program confirms the agreement with the experimental results.
