A Half Bridge CLL Resonant DC/DC Converter

An introduction to LLC resonant half-bridge converter

Although in existence for many years, only recently has the LLC resonant converter, in particular in its half-bridge implementation, gained in the popularity it certainly deserves. In many applications, such as flat panel TVs, 85+ ATX PCs or small form factor PCs, where the requirements on efficiency and power density of their SMPS are getting tougher and tougher, the LLC resonant half-bridge w...

Novel half-bridge resonant converter topology realized by adjusting transformer parameters

This paper shows a new direction as to how the transformer parameters may be best utilized and presents the performance and control of novel dc/dc and ac/dc converter topologies. All three inductances of a transformer have been utilized to realize a 3 topology having excellent characteristics and requiring no external inductor. For half-bridge topology, the capacitor used for the purpose of inp...

AN-9729 — LED Application Design Guide Using Half-Bridge LLC Resonant Converter for 100W Street Lighting

This application note describes the LED driving system using a half-bridge LLC resonant converter for high power LED lighting applications, such as outdoor or street lighting. Due to the existence of the non-isolation DC-DC converter to control the LED current and the light intensity, the conventional PWM DC-DC converter has the problem of low-power conversion efficiency. The half-bridge LLC co...
