Light Emitting Diodes (LEDs) with their current performances have been proved to be the most suitable solution for street lighting applications. Nowadays, a topic of interest in this context is the design for electronic driver in order to take the advantage of LEDs performances. However, requirements such as high power factor, long life time, accurate current control and high efficiency pose ch...

This thesis presents High frequency Soft Switching DC-DC boost Converter. The circuit consists of a general Boost Converter with an additional resonant circuit which has a switch, inductor, capacitor and a diode.In general Boost Converter circuits have snubber circuits where switching losses are dissipated in external passive resistors; which is known as hard switching. As the switching frequen...

In the energy distribution grid of electric vehicles (EVs), multiple different voltage potentials need to be interconnected, allow arbitrary power flow between various sources and electrical loads. However, potentials, galvanic isolation is absolutely necessary, either due safety reasons and/or grounding schemes. This paper presents an isolated three-port DC/DC converter topology, which, in com...

This paper investigates the reliability of an isolated buck-boost DC-DC converter (IBBC) based on configuration a series resonant (SRC). Two approaches are employed to predict IBBC reliability, which MIL-HDBK-217F handbook and FIDES guide. The latter approach can take into account how failure rate components physics is influenced by varying yearly mission profile. To do this, thermal loading ea...
