Hi all,
I a currently reaching the deadline for my Senior project and I am trying to get this to work. I am working on a DC/AC converter (Pure sine wave) and I am currently attempting to couple a boost converter with the H bridge. The DC/DC converter has a PI feedback control with a microcontroller (PSoC 5LP) performing both PI control and SPWM generation.
My problem is: Whenever I couple both the boost converter and the H-Bridge, the output of the boost converter drops by a significant amount even though the controller compensates for load changes.
Below is a a picture of the LtSPICE schematic of both the boost converter and the inverter. Note I did not include the PI controller for this part but below the schematic, there is a picture of the simulink model for the converter control. For the feedback system, I used a voltage divider network.
Any recommendations or thoughts as of what could be causing this?
