    Hi all,

    I am currently working on this project that required me to build a Dc-Dc boost converter cascaded with a inverter to interface to grid.

    To test the stability of my converters which i had build and for safety reasons, I connected a low input voltage of 5V to the input of Dc-Dc boost converter. The boost converter boost up the voltage to approximate 16V dc. As the converters are cascaded together, the 16V boosted voltage is fed into the input of my inverter. The inverter should produce a rms value of 16V at 50Hz. When I measure my voltage output across the resistive load, its only display a rms 6V ac at 50Hz.

    I am using an Ac LC filter design for my inverter. From my observation, the voltage drop across the inductor is 10V ac which explain why the output voltage is low as there is a high voltage drop across the inductor.

    I hope that someone can kindly advise me on this issue. Appreciated.

    It will be difficult to suggest a course of action other than to post your schematic first.
