Interesting ... was hoping for a ripple-free DC out, but that's going to take 3-phase PFC AC/DC converter.
For a moment I thought you referred to three windings required in series (zig-zag), but realized and then read you meant after rectification. Oh, that's not zig-zag, need 3 pairs in WYE, not 3 in series or you get zero:
Straight line at zero was sum without rectification, ripple on top is with.
function sumSine
%SUMSINE Study effect of rectifying and summing sine wave.
% Detailed explanation goes here
% Usage:
%
% sumSine
%
freq = 60; % Hz
time = 1; % second
stepsize = 1/10000; % seconds
t = 0:stepsize:time;
phaseAngle = 2*pi/3; % 3-phase
phaseL1 = 0; % radians
phaseL2 = phaseL1 + phaseAngle;
phaseL3 = phaseL2 + phaseAngle;
amplitudeVrms = 120; % volts
amplitudeVpeak = amplitudeVrms * sqrt(2);
L1complex = amplitudeVpeak * exp(-j*(2*pi*t+phaseL1));
L2complex = amplitudeVpeak * exp(-j*(2*pi*t+phaseL2));
L3complex = amplitudeVpeak * exp(-j*(2*pi*t+phaseL3));
plot(t,real(L1complex));
hold on
plot(t,real(L2complex));
plot(t,abs(real(L1complex))+abs(real(L2complex))+abs(real(L3complex)));
end
Works in volts. I think it shoves current through transformers when they weren't planning to source it, much like your papa/momma/baby bear transformers. Or does that go through diodes? Must be sucking current not in proportion to voltage, anything but 1.0 PF.
LTSpice, paralleled small ripple as you say. Gulps of current from each phase when it is above others.
Series, double voltage and still gulps of current, but not sitting at zero. Always a peak but not positive or negative.
Warpverter just transfers it to primary. Instantaneous current change generates back EMF at least due to leakage inductance.
Hate to think what HF inverter would do faced with that.
