- Add an ‘Inverse Park Transform’ block, connecting it to the output of the Park Transform block to convert ‘dq’ components back to ‘ABC’ components.
- Use a ‘Sinewave block’ to generate a sinusoidal reference waveform, adjust its frequency and amplitude as needed.
- Compare the output of the Inverse Park Transform block with the sinusoidal reference using a Comparator block.
- Apply a logic threshold using Gain and Relational Operator blocks. Amplify the Comparator output with a Gain block, subtract a threshold value using a Sum block, and compare the result to zero with a Relational Operator block.
- Drive a Pulse Generator block with the binary PWM signal from the logic threshold, configuring it to generate pulses based on the binary input.
- Connect the output of the Pulse Generator block to your boost PWM block or the component that requires the PWM signal.
how can i connect the output of park^-1 transform to a sinusoidal pwm developed for qzsi

we know that the output of inverse park transform will generate 0 and 1 signal. my question is that how to connect these output to sinsoidal pwm in matlab simulink. i have developed a simple boost pwm to generate 7 pulse signal for bidirectional quasi z-source inverter.so, can anyone provide solution for this.

Hi Angelin,
I understand that you are trying to use the output of the inverse park transform to generate a 0 and 1 signal and then use it in the sinusoidal PWM in MATLAB Simulink.
The output of the inverse park transform in electrical systems typically results in continuous three-phase signals, representing the voltage or current in a three-phase system, rather than generating binary 0 and 1 signals.
The inverse Park transform is used in control systems to convert the ‘dq’ components (rotating frame) back to the ‘ABC’ components (stationary frame) in a three-phase system. The output of the inverse park transform is typically continuous Analog signals representing the ABC components.
To connect the output of the inverse park, transform to a sinusoidal PWM in MATLAB Simulink, you can follow these steps:
To know more about inverse transform block, please refer to the following MATLAB documentation.
Hope it helps.

Thanks alor for briefly replying.
But, where or how the shoot through/ non-shoot through states of the QZSI are adjusted.
