What is resonant inverter with energy dosing?

1. Introduction Resonant inverters with energy dosing (RIED) are a modification of classical resonant power circuits well known in the field of power electronics, and they are characterized by high-efficiency power conversion at constant power, independent of load variations [1, 2].

Why do inverters use resonant operation?

operation at very high frequencies and to meet other requirements. For example, the well-known class E inverter uses resonant operation to provide zero-voltage witching and enable the use of (relatively) slow gating wave-forms. Moreover, it requires only a single ground-referenced switch, and abso

What are the state variables of a resonant inverter?

where the state variables are as follows: iLR is the current in the inverter’s AC circuit (current through the resonant inductance), i e is the current through the load, uC is the voltage across the load (the voltage across the load capacitor C), and are the voltages on the resonant capacitors.

What are the future research directions for Resonant inverters?

Future research directions include parametric analysis of the influence of circuit element tolerances on optimized and non-optimized devices, as well as the application of artificial intelligence techniques, such as neural networks, for the fully automated design of this type of resonant inverters.

What is a single-ended resonant converter?

The study discusses single-ended resonant converters, such as class E inverters, for low- and medium-power applications in wireless power transfer (WPT). The main advantage of these topologies is their compactness, low switching losses, and cost-effectiveness since they use only one switch with a simple driver.

What are the features of a high frequency inverter?

to operation at very high frequencies and to rapid on/off control. Features of this inverter topology include low semiconductor voltage stress, small passive energy stora e requirements, fast dynamic response, and good design flexibility. The structure and operation of the pr posed topology are described, and a design procedure is introduced. Exp
