Pulse width modulation for AC_DC 1-phase inverters, tabulated synchronous mode (phase-angle instead of time).
v_AC_eff = u*v_DC/sqrt(2) AC effective voltage u[1] ≤ 1 for pure sine-modulation, but u[1] > 1 possible. u[1] = 1 corresponds to: AC amplitude = v_DC gates[1:2] phase-module 1 gates[3:4] phase-module 2
