A novel design of switched boost action based multiport converter using dsPIC controller for renewable energy applications

Abstract

Traditionally the grid supplies only a particular voltage to the load, but today we are using 'n' number of loads with different voltage rating and converters. So, the conversion of the generated AC voltage into several stages of DC voltage before reaching the load is required. In this paper, the Multi Port Converter (MPC) is proposed, which is capable of converting a single valued AC voltage into several stages of DC voltage. The feasibility of employing of converter level switch node, as an interface to numerous output stages is examined in this paper. The connecting of several outputs at the identical node is accomplished by the use of time-division multiplexing technique. In this study, the input power is multiplexed into separate ports via a phenomenon known as Switching Boost Action (SBA). The prototype was developed for converting the 240 V, 50 Hz, single phase AC supply into two outputs and the 12 V DC supply which can fed to the loads, that can be stored in batteries for future use. This paper has been proposed to design SBA based MPC using dsPIC controller for renewable energy applications.
