Photovoltaic powered DC-DC boost converter based on PID controller for battery charging system

Abstract

The input voltage of battery charging system is always above the battery nominal voltage and it should be remained constant. But it depends on the type of input voltage sources. A battery charged directly by photovoltaic (PV) module as the input voltage source can cause the output voltage of PV module or the input voltage of battery charging system can fluctuate, because the output voltage of PV module depends on the solar irradiance. This problem can be solved by installing DC-DC boost converter between the PV module and battery. This paper presents a DC-DC boost converter based on PID controller for battery charging system. It is designed for the input voltage of 12V and output voltage of 14.7V system because it is applied to charge a 12 V, 7 Ah lead acid battery. Based on the simulation result of battery charging system shows that the output voltage of DC-DC boost converter can be remain around 14.7 V. It is due to the PID controller can damp the voltage oscillation and remain its steady state voltage. The time needed by the DC-DC boost converter to charge the battery in the fully charging condition is 1 hour: 3 minutes: 37seconds.

Effect of Temperature and Solar Irradiance on the Performance of 50 Hz Photovoltaic Wireless Power Transfer System

“…In Figure 5a, the distance between the TC and RC was dtr, indicating that the mutual inductance between both coils (Mtr) was obtained from Equation ( 6) [4]. Based on Figure 5b, the distance between the TC and RC was dtr, showing that Mtr was obtained through Equation (6).…”

“…This radiation is divided into two parts, namely (1) solar irradiance, the sun power density with a unit of W/m 2 , and (2) solar irradiation, the sun energy density with a unit of J/m 2 or Wh/m 2 [1][2][3]. The component of solar irradiance is very important in the conversion of sunlight to electrical energy, using a PV module [4][5][6], which has a wide global application. This module is often applied in the DC application systems were observed according to [7][8][9], where their utilization in DC loads through the DC-DC converter.…”

Design And Comparison of Mppt Controller for Pv Systems

“…As a result, even if the maximum power point (MPP) is attained from photovoltaic panels, it is extremely difficult to transfer the maximum power generated by them straight to the loads on a continuous basis. Because the PV system is impacted by the intensity of sunlight and the temperature, the load curve must be adjusted in response to weather variations (Irwanto et al, 2020;Palanisamy et al, 2019). We can achieve this by adding an electronic system whose location is between the solar panels and the load.…”

Optimum Sizing and Performance of Fuel Cell Stack Integrated by Boosted DC-DC converter for Running DC Load

“…The boosted DC-DC converter is designed with efficiency of 100%, it means that the output power of 50 W equals the input power. It has parameters of an inductance of inductor, L; a capacitance of capacitor, C and a resistance of resistor, R with their formulations to obtain the required values as stated by [10]. The boosted DC-DC converter is designed as open loop system with system frequency, f of 25 kHz to maintain in the condition of the input voltage of 12 V, the output voltage of 24 V and the output power of 50 W.…”
