The main aim of this document is to verify the operation of the closed loop control for power converters through by HIL technical whose topologies are the buck, boost, and the buck-boost. This includes different signals properties, for example, input to the switching device (PWM), the response voltage and the current of the inductor. To develop objectives as mentioned, three main stages are raised:...
This paper deals with the battery energy management for the case of isolated locations when they are equipped by wind turbines using energy storage devices. To cover the shortfall or the overflow of those kind of generation caused suddenly by the wind variation, the energy storage device is a necessity to improve our isolated wind farm. From this condition a great part of the energy distribution is...
A fuzzy controller for closed loop control of DC drive fed by DC-DC converter (Chopper) is designed and presented in this paper. This system has been designed to have two loops with an inner ON/OFF current controller and an outer fuzzy speed controller. The later is used to change the duty cycle of the converter and thereby, the voltage fed to the DC series motor regulates its speed. The performance...
This paper presents the small signal model and closed loop control design using average current control for an L-L type active-clamped zero-voltage switching (ZVS) current-fed isolated DC-DC converter. State-space averaging technique is used to derive the small signal model. The controller is designed for fixed-frequency duty cycle modulation and works for wide input voltage and load variation. A...
DC-DC converters have wide several applications in electrical industry, they can be employed for varied DC voltage usages and stabilization or the control of DC voltage of a battery or it can be a component of a complex converter to control the intermediate or output voltages. Due to their switching property included in their structure, DC-DC converters have a non-linear behavior and their controlling...
