blockPWMsyn
Sine PWM synchronous mode, 3phase
Extends from Partials.PWMsynBase (Sine PWM synchronous base).
Information
Pulse width modulation for AC_DC 3-phase inverters, synchronous mode (phase-angle instead of time).
|v_AC| = u*sqrt(3/2)*v_DC/2 AC voltage norm u[1] ≤ 1 for pure sine-modulation, but u[1] > 1 possible. u[1] = 1 corresponds to AC single-phase amplitude = v_DC/2 gates[1:2] phase-module a gates[3:4] phase-module b gates[5:6] phase-module c
