This paper introduces a technique to reduce the output impedance in the PWM buck converters with voltage-mode control (VMC) without requiring low Equivalent Series Resistance (ESR) output capacitors. Proposed technique uses the infinity norm ( ) to convert the problem into an optimization problem. Obtained optimization problem is solved with the aid of Genetic Algorithm (GA). The proposed technique is applied to a sample buck converter operating in Continuous Conduction Mode (CCM). Simulink simulation is used to test the suggested method. Simulation results showed a considerable decrease in the low frequency region of output impedance. Such a decrease in output impedance is very desired for low voltage high current loads like computer CPU’s.

In this study, a test device is developed to measure the capacities and performances of high capacity battery banks and to detect broken cells. Batteries lose their performance over time due to their chemical properties, storage and usage conditions, production technologies. Some batteries may even become completely unusable long before the promised life cycle. Through this test device, the instant capacity of the battery banks is measured. Based on the data obtained, quantitative data such as state of health and nominal energy of the battery bank are calculating. It is determined whether the battery bank will meet the need according to its intended use. In this way, it is ensured to prevent possible losses by determining the battery cells or groups that need to be changed.

“…For the lossless power stage, the input power is also constant; therefore, the input current is inversely proportional to the input voltage, so the differential input resistance is negative. The input filter design in such a situation has been considered in various studies [17][18][19][20][21][22][23].…”

The main goal of this study was to derive small-signal models of the input characteristics of buck, boost, and flyback converters working in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The models presented in the paper were derived using the separation of variables approach and included the parasitic resistances of all converter components. The paper features a discussion about the limitations of the model accuracy. The presented characteristics were obtained by calculation and verified by measurements. The input characteristics of converters are essential in the design of converters used in Power Factor Correction systems as well as in maximum power point tracking systems (MPPT).
