Based on the needs for high power densities and ultra-high efficiencies, the popularity of resonant converters has never been as high before. However, by pushing the upper limit of switching frequency to higher levels, their beneficial soft-switching

This paper discusses major aspects to be addressed for reliable determination of the transfer function of a frequency controlled converter through square wave perturbation. The square wave as a multi frequency perturbation allows to determine the tra

The class of resonant converters is very attractive due to its ability to achieve nearly lossless switching by using zero current or zero voltage switching (ZCS/ZVS) for the switching devices in the input bridge. Since most switched-mode power suppli

This paper describes two basic approaches to calculate the small signal behavior of the resonant LLC-converter. There are no limitations to the underlying time domain model, simulations based on Spice are possible. The theory behind the `Virtual Netw

While resonant converters have been gaining much attention within the recent years, their exact mathematical description is rather complicated. Thus, simplified calculation methods are very attractive, e.g. the First Harmonic Approximation (FHA). Alt

Today, many electrical applications use the DC-DC buck converter topology as point of load (POL) converter with synchronous rectifiers to provide the desired output voltage for different loads and components [1-3]. While its efficiency is usually opt

Due to the increasingly demand for highly efficient, cost-effective and low-profile applications, resonant converter topologies are massively gaining in importance. With the LCC and LLC converter, the two most promising topologies of this converter c

Often data sheets provide only poor information about the recovery behavior of ultra-fast diodes. On the other hand, existing diode models do not predict the real characteristic for all diodes. Nevertheless, due to its importance, this behavior needs
