Powergui error - invalid port dimensions

I was able to get an equivalent model, with a different control subsystem to simulate.
With a new control I am getting the error in the image, stating the powergui vector dimensions are now incorrect.
The model is a bidirectional DC-DC converter; before there were no PWM blocks as the control system handled that, they needed to be added here.
Taking a stab if anyone has any answers on here.

Hello Greg,
the gate signal has 6 pulses in it. These need to be split out and provided individually to the switches, or use the universal bridge block and set it to be an inverter.

Apologies for asking on an old question however I'm getting the same error as Greg did (albeit for a different application as I'm modelling a wind turbine) however I'm not sure what you mean by splitting the 6 pulse in the gate?
Any clarification would be appreciated however no worries if not.
Best,
Abd

Hello Abd,
you need to create the PWM signals for each switch, and if the switches are part of a converter block, merge them with a mux block.. There are a few examples of how to do this.

Joel
