Public Functions Documentation¶

function sstep_bridge_map¶

Map requested phase voltages to leg compare values (averaged power stage).

void sstep_bridge_map (
    enum sstep_topology topology,
    sstep_acc_t va,
    sstep_acc_t vb,
    const struct sstep_gain * inv_vbus,
    sstep_acc_t vbus,
    uint16_t period,
    struct sstep_bridge_out * out
)

The voltage vector is scaled down with its direction kept when the stage cannot produce it: full bridge |a|, |b| <= 1, shared leg max(a,b,0) - min(a,b,0) <= 1, a and b relative to the measured bus voltage. Shared leg: common leg centred.

Parameters:

topology Power stage topology (compiled in).
va Requested phase voltages [pu of V_base].
inv_vbus V_base / bus voltage.
vbus Bus voltage [pu of V_base], 0 .. 2.
period Compare value for 100 % duty cycle.
out Result.
