vtechworks.lib.vt.eduLLC Resonant Converter 95 loss problem of PWM converter. Even with Zero Voltage Switching technique, the turn on loss could be minimized; turn off loss still limits the capability of the converter to operate at higher switching frequency. Resonant converter, which were been investigated intensively in the 80's [B1]-

www.onsemi.comRectifier Controller for LLC Resonant Converter NCP4318 NCP4318 is an advanced synchronous rectification (SR) controller for LLC resonant converter with minimum external components. It has two gate drivers for driving the SR MOSFETs rectifying the outputs of the secondary transformer windings. The two gate drivers
TEA19161 and TEA19162 controller ICs
www.nxp.comMost LLC resonant converter controllers regulate the output power by adjusting the operating frequency. The TEA19161T regulates the output power by adjusting the voltage across the primary resonant capacitor. The result is accurate state control and a linear power control. Using a voltage divider, the primary resonant capacitor voltage provides ...

Voltage gains of 2- and 3-element resonant topologies with voltage sources are analyzed in this paper. Three fundamental resonant elements – series resonance (SR), parallel resonance (PR)
An introduction to LLC resonant half-bridge converter
www.st.comAN2644 The LLC resonant half-bridge converter 7/64 In resonant inverters (and converters too) power flow can be controlled by the switch network either by changing the frequency of the square wave voltage, or its duty cycle, or both, or by special cont rol schemes such as phas e-shift control. In this context we will focus
