Using Constant Switching Frequency Control in Linear-Assisted DC-DC Switching Converters for Photovoltaic Solar Regulators
This article shows the proposal of a linear–assisted converter or linear–&–switching hybrid converter with a constant switching frequency for photovoltaic solar DC-DC regulators. The control loop of the system is based on the current–mode technique. The main disadvantage of a converter with current– mode control is the inherent instability of the loop when switch duty ratios are greater than 0....
متن کاملLinear–Assisted DC/DC Converters with Modified Current-Mode Control Applied to Photovoltaic Solar Systems
Linear-assisted DC/DC converters are structures that allow to take advantages of the two classic alternatives in the design of power supply systems: Voltage linear regulators (classic NPN topology or LDO –low dropout–) and switching DC/DC converters. This paper shows the proposal of a modified current-mode one-cycle control for linear-assisted DC/DC converters. The modified current-mode onecycl...
متن کاملDC Microgrid Protection in the Presence of the Photovoltaic and Energy Storage Systems
In recent years, most of the loads and distributed generations are connected to the AC grid through the power electronic converters. Using the DC grid beside the AC grid can reduce the conversion stages and power losses. Protection of the DC grids is a challenging issue because of the new structures of DC grids and fast transients of the DC faults. This paper studies the protection of the low v...
متن کاملA Double Input DC to DC Buck-Boost Converter for Low Voltage Photovoltaic/Wind Systems
A Double input DC to DC converter for low voltage energy sources applications is proposed in this paper. The proposed converter is buck-boost converter which can step up or step down the input voltage according to output voltage required at load end. The converter is able to boost up voltage of energy sources such as solar photovoltaic and wind energy system of relatively low voltage. The conve...
متن کاملDevelopment of a photovoltaic low voltage DC microgrid for buildings with energy storage systems
In order to develop a sustainable datacenter, which would help to validate energy management and task scheduling algorithms, a low voltage direct current (LVDC) microgrid (MG) has been deployed in the ADREAM Building-Integrated Photovoltaic (BIPV) of the LAAS-CNRS in Toulouse, France. This MG is composed of a 1 kWp PV source, 300 Ah – 36 V lead-acid batteries, 330 F – 48 V supercapacitor (SC) p...
