full load Bo Yang Chapter 5 Improvements of LLC resonant converter 146 The drawbacks of this method are 1 Two magnetic cores are needed which results in more components count and connections 2 High magnetic loss caused by high flux ripple in magnetic structure 3 Large footprint is needed for ...
It is because the wave form of LLC resonant converter is different from PWM. The objective of this research is to reduce the power dissipation and physical size at the same time. In this thesis, a novel current driven synchronous rectifier with saturable current transformer and dynamic gate ...
I. Introduction – the LLC Converter Historically, buck-derived topologies have dominated the design choices in DC-DC converters. These topologies include the buck, push-pull, forward, half-bridge, full-bridge, phase- shifted full-bridge, etc. While it seems that there is an endless myriad of...

the output current regulations functions. This ensures low variation in the output voltage and current and allows for low THD, high power factor and a greater ability to withstand AC line perturbations. The multi-mode operation of PFC converter provides excellent efficiency over the whole load ...
After the soft start, a voltage controller is used to control the full bridge switching frequency. The system reaches the desired 300 VDC output after 20 ms. The plot below shows the transient simulation of the LLC converter from startup. PLECS thermal descriptions are provided for the ...
AN2450 Application note LLC resonant half-bridge converter design guideline Silvio De Simone Introduction The growing popularity of the LLC resonant converter in its half-bridge implementation (see Figure 1 on page 4) is due to its high-efficiency, low level of EMI emissions, and its ab...
The PFC converter may run into CCM operation for a longer period due to shorted bypass diode, heavy load step that is out of specification or very low input voltage that is out of the normal operating range. When CCM occurs, the magnetizing current in the PFC choke does not have a ...
converter comprising an LLC resonant DC/DC converter which receives the DC bus voltage and provides an output voltage; and an LLC controller;the LLC resonant DC/DC converter comprising first and second half-bridge legs, which are operable in an half-bridge mode and in a full-bridge mode;the...
