LLCSim

C++ Simulation Library for LLC resonant converters by Francisco Piernas Díaz

This is a simple header library to perform time domain simulations for Half-Bridge and Full-Bridge resonant LLC converters.

Create a circuit with:

    llc circuit1(Cr,Lr,Lm,Ls,C,R,Ts,V,type,freq);

    where:
        Cr: resonant capacitor value, example 13e-9
        Lr: resonant inductor value, example 150e-6
        Lm: primary inductance value, example 448e-6
        Ls: secondary inductance value, example 1.7e-6
        C: output capacitor value, example 600e-6
        R: load in ohms, example 0.86
        Ts: time step, 1e-9 should be enough
        V: input voltage, example 385
        type: LLC_FULL_BRIDGE or LLC_HALF_BRIDGE
        freq: working frequency

Once the object is created, call successively circuit1.step() to advance a time step.

The circuit created is an equivalent version of the real circuit where C and R are
reflected to primary.

Check circuit status with circuit1.state.stateVector(i), with i being:
    0: Cr voltage
    1: Resonant current
    2: Primary current
    3: Output voltage

Check real output voltage with circuit1.Vout

You can change frequency on simulation time by calling circuit1.set_freq(unsigned int freq).
It is recommended to change frequency only when previous period ends

To change the load call change_R(double R);
