“…The transformer plays a critical role in the operation of the converter, since its magnetising and leakage inductances define the resonant frequencies. The most used models for a three winding transformer are the extended T-model, shown in figure 2a, as used in [1] and the cantilever-, or ∆-model [7] of figure 2b. A resistance R 0 is added across the primary winding to account for core losses in the transformer.…”

Abstract-Feedback sensor isolation is often an expensive necessity in power converters, for reasons of safety and electromagnetic compatibility. A disturbance observer-based control strategy for a dual-output resonant converter is proposed to overcome this problem. Current control of two LED loads is achieved through estimation rather than measurement. Robustness against temperature changes, which have significant impact on the behaviour of the LEDs, is achieved through estimation of offsets in the forward voltages of the LED-strings. The power converter and LEDs are modelled accurately to obtain a good estimation accuracy. The whole implementation is steered towards a low cost solution.

“…It should be clarified that the notation used to indicate the impedance matrix is representative of only the reactive component of due to the equivalent inductance; the extended cantilever model in [15] is formulated only with consideration to inductances. An extension which allows for full Laplace domain circuit elements can be found in [18], [19], however in the idealized case considered here, parasitic resistances and capacitances are assumed to be negligible.

Capacitor parasitic inductance often limits the high-frequency performance of electromagnetic interference (EMI) filters in both common-mode (CM) and differential-mode (DM) filtering domains. However, these limitations can be overcome through the use of specially-coupled magnetic windings that effectively nullify the capacitor parasitic inductance. This document explores the use of a single coupled magnetic winding to provide inductance compensation for multiple capacitors (e.g., both DM and CM capacitors) simultaneously, reducing the number of coils previously required. The substantial advantages of this method are illustrated both in a proof-of-concept test circuit and in an improved version of an existing EMI filter. The coupling between multiple inductance compensation windings in a single filter enclosure is also investigated.Index Terms-Cantilever model, capacitor parasitic inductance, coupled magnetic windings, electromagnetic compatibility (EMC), electromagnetic interference (EMI), EMI filter, inductance cancellation, inductive coupling, radio frequency interference (RFI).
