During the development of a power converter, INFINERGIES challenged the standard mathematical model for LLC resonant converters. This model uses a resistive loads, and is not appropriate in many circumstances.Many charges are power converters (such as POL converters), that behave as a constant-power charge. Others, such as batteries, have their behaviour dictated by the control law, and a constant power charge is the fastest.
This is why we developed a new mathematical model for LLC converters for this type of charges. We published our results in the November 2019 edition (page 58) of Bodo's Power, the magazine for power electronics.
