What is the relationship of resistance and current according to Ohm's law?3 answersAccording to Ohm's law, the relationship between resistance and current is defined by the equation V=IR, where V represents voltage, I represents current, and R represents resistance. Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. This means that as the resistance increases, the current decreases, and vice versa. The relationship between resistance and current is fundamental in electrical systems and is used to calculate the behavior of circuits and components. Ohm's law provides a foundational understanding of how current and resistance are related in electrical systems.
What is the effect of load resistance on the output voltage of a converter?3 answersThe effect of load resistance on the output voltage of a converter is dependent on various factors. In the case of a class-E resonant inverter, the load impedance and power factor strongly influence the zero-voltage switching (ZVS) and zero-derivative switching (ZDS), which can significantly reduce the conversion efficiency. For regulated converters, the load interactions are reflected in the converter dynamics through the internal open-loop output impedance, especially for capacitive and resonant-type loads. In a boost converter, the output voltage regulation for a constant power load is achieved through a nonlinear control strategy that transforms the nonlinear average dynamics of the inductor current into a linear average dynamics, with the resistor contributing to system stability and the voltage source indirectly regulating the output voltage. The impedance-to-voltage converter utilizes an operational amplifier and a feedback impedance circuit to convert impedance to voltage, with the shielding element reducing noise on the signal line.
How does the load resistance affect the output current of a converter?5 answersThe load resistance has a significant impact on the output current of a converter. The dynamics and performance of a regulated converter are influenced by the load impedance, which is reflected in the converter's internal open-loop output impedance. The converter's control bandwidth can be reduced when the loop gain is much higher than unity and the internal closed-loop output impedance is equal to or greater than the load impedance. In peak current-mode control, measuring and utilizing the load current can improve control by reducing the output impedance and making the control-to-output transfer function almost invariant for different loads. Load current feedforward control technique can also minimize the impact of the Right-Half-Plane-Zero (RHPZ) in certain converter topologies, such as boost converters, by estimating the load current and combining it with the control loop.
How does converter tuning affect the oscillations due to lack of system strength?5 answersConverter tuning can have an impact on the oscillations caused by the lack of system strength.

The paper by Urdal et al. raises questions about system strength in an HVAC system with non-synchronous generation (NSG) and the financial consequences of constraining RES production. Pareschi et al. show that different solutions can be obtained for resonant class-E dc/dc converters, leading to variations in the size of inductors/transformers, oscillation frequency, and converter efficiency. Mohiti et al. present a genetic algorithm-based method for the allocation and tuning of TCSC to improve poorly damped oscillations, which can be applied in large systems without requiring all system data. Stumpf et al. propose a stability analysis method for power factor correction converters, considering the effect of non-ideal circuit elements and the addition of a stabilizing signal to extend the stable range.
