A novel MPPT control method using optimal voltage of PV with secondary phase-shift PWM control DC-AC converter

Abstract

In this paper, a novel maximum power point tracking(MPPT) scheme is proposed and simulated using a high-frequency AC link converter with secondary side PWM cdntrol scheme. Having an eye on that the optimal voltage point of solar cell is in proportion to its panel temperature, with operating the power converter whose operating point keeps its input voltage at the maximum power point, the maximum power point becomes tenderly possible to be tracked. As the results of that, we got a hopeful answer to apply to practical field, furthermore the secondary phaseshift PWM control DC-AC converter shows us a special quality to apply for a solar generation system.

Maximum Power Point Tracking of Photovoltaic System for Traffic Light Application

“…Figure 18 shows the output voltage of the DC-DC converter after being filtered, where we can keep output of the DC-DC converter oround 16.5 V. This voltage is a swing point of maximum power point of PV module. This method is known as MPPT technique uses Constant Voltage Control [13]. This value had has error of 2.6%, if we compared with maximum power point voltage of PV module in Table 1 that is 16.9 V.…”

A Multiple-Input DC/DC Converter for Renewable Energy Systems

“…Recently, clean energy resources such as wind turbines, photovoltaic arrays or fuel cells have been exploited for developing renewable electric power generation systems [1][2][3]. The multiple-input DC/ DC converter shown in Figure l(a), is useful for combining several energy sources whose power capacity and/ or voltage levels are different to obtain well-regulated output voltage [4][5][6][7].…”
