In this study, a modified carrier is proposed to generate PWM gating signal. Proposed PWM method reduces total harmonic distortion (THD) of the output voltage of inverter up to 5.8% than the traditional triangular carrier based PWM. Major harmonic components in output voltage are less in magnitude when proposed PWM technique is applied to inverter. Fundamental component of output voltage is also higher...
A modified multilevel inverter (MLI) structure has been presented for Photovoltaic (PV) fed 2.3 kV micro-grid applications. To feed the cascaded multilevel micro-grid connected inverter (CM-MGCI) voltage, a PV array is designed considering the environmental effects of Bangladesh. We have estimated the performance of the classical and a modified cascaded H-bridge (CHB) MLI with level-shifted carrier...
Different technical issues regarding the use of Li-ion and lead acid battery in solar photovoltaic system is presented in this study. Economic comparison for using these two types of batteries in solar home system (SHS) of Bangladesh is also presented in terms of net present cost (NPC). Li-ion batteries, especially LiFeSO4 batteries, are technically more advantageous for use in intermittent solar...
Solar radiation at Patenga, Chittagong is predicted by using record of bright sunshine hours of that place. Monthly average solar radiation is calculated from Angstrom-Prescott equation. The coefficients of that equation is found as a = 0.1688 and b= 0.5869. Patenga is a coastal area of Bangladesh and has promising potential of hybrid solar-wind based electricity. Solar radiation data is required...
