As the shoot through time is used for buck-boost operation of z source converters, so how can I generate PWM for converter switches with desired shoot through time?
Depending upon the structure of the required pulse, you may use digital circuits such as flip-flops and timers. For that, you may consult any book related to digital fundamentals/circuits.
But I require variable shoot through time so that the output voltage can be buck or boosted. For a simple Voltage source converter, the pulse can be generated easily but in case of Z-source converter, the shoot through period may or may not be required. So In Z-source converter how to generate the pulses.
Dear Kartik,
Greetings of the day, it is possible to vary the shoot through period, so that the inverter can work in buck mode or boost mode. go through the book, " HIGH PERFORMANCE CONTROL OF AC DRIVES WITH MATLAB/SIMULINK MODELS", chapter 3, page 117. It will give you idea about the pulses for the shoot through state. If still have problem, contact me on [email protected]. May be the attached file will help you.
Regards
I have simulated the simple boost control scheme for a single phase ZSI. Now if I want to control the DC link voltage/Capacitor voltage and control from AC side too than a closed loop scheme is required. So how can I include the controller outputs from both sides (DC side loop and AC side loop) for generation of switching pulses so that I have a shoot through duty ratio which changes according to the actual output voltage/DC link voltage.
