Your schematic has a load circuit different from the paper. It doesn't make sense to me at first sight.
The paper is describing a boost mode PFC chopper with voltage output. According to the given definition it's a "voltage type" rectifier, output voltage is always higher than the input voltage. The latter is commanded by the antiparallel IGBT diodes, which are confusingly hidden in your schematic.
Which output and current waveforms do you expect?
Actually i move a little... is this correct function for single phase current rectifier?
schematics:
View attachment 144684
output:
View attachment 144685
So can someone tell me this is proper function? Im not sure why i got on output only around 0,5V but i think that output voltage curve correspond with output i got in theory....is that correct?
To understand the current rectification, you must display it along with voltage during the deadtime for PWM commutation. L/R decay times and LdI/dt will create spikes that may be clamped by diodes. Schottky diodes will have more C but lower Vf.
Does't work. Unlike SCR, IGBTs have no reverse blocking capability. They are either equipped with a built-in reverse diode (APT25 has it as far I'm aware of) or they have a low reverse breakdown voltage of a few 10 volts and must be supplemented with an additional diode to protect it.and im using IGBT instead of thyristors
Question is if the circuits works with real IGBT too.so now its all right and working as intended
L/R=T=100us
that's why
I checked that the PSPICE APT25GF model is missing a reverse diode, in accordance with the symbol but despite of the built-in diode in actual APT25GF part. To achieve reasonable circuit operation, it's necessary to supplement rectifier diodes, see my previous comment about reverse blocking of IGBT.
The generic PSPICE IGBT model doesn't model reverse breakdown correctly, so the simulation results are completely different from expectable real circuit behavior, either for IGBT with or without built-in diode.
I agree with SunnySkyguy that the output inductor time constant should be increased to get continuous current, but presently the circuit is behaving just unrealistically due to the reverse diode problem.
