- Abstract
- Power supply modules can be connected in parallel to build up a complex power system. Connecting many converters is more beneficial as compared to a single larger power unit because of components stress, modular implementation, flexible power requirements, and design variations. All of the above benefits can be achieved as long as the load current is distributed between the converters in a controllable manner. Digital feedforward control method is derived and proposed in this article for parallel connected buck-boost converters operating in Discontinuous Conduction Mode, for maintaining the output voltage and to control the load current distribution amongst them. Proposed feed-forward control method is paralleled with two well-known current control schemes i.e. the Average Inductor Current Mode Control (AICMC) and the Hysteresis Current Control Method. MATLAB results shows that our proposed scheme demonstrates superior results in term of the harmonics reduction and power factor as linked to the other two methods.
