Abstract
Performance, efficiency, cost of the power converters and their associated control, are important considerations for the commercialization of renewable power sources. In view of this, this paper proposes a reliable and low cost power electronics interface for photovoltaic energy systems, using a single DSP controller. The proposed approach achieves the following: (a) integrate the dc-dc converter control and inverter control by utilizing a single, low cost, fixed point Digital Signal Processor (DSP controller) (b) implement a fast converging MPP tracking method in the dc-dc converter stage (c) reduce the size of the dc-link capacitor by using a modified pulse width modulation (PWM) technique for single phase inverter control.
