Hi,
I am currently doing my Master project and unfortunately did a rookie mistake.
My DC motor is mechanically linked to a loaded PMA (wind turbine generator) and I need to run it at a variable speed. All this is built, however when choosing my PSU, I forgot to take into account the stall...
Ok thank you for the greatly precise and clear explanation. I will definitely look into this system in detail. Should the additional resistor (theoretically 39 ohms/100W) then be added in parallel to this current sink system (I would guess before the MOSFET)?
EDIT: I hadn't seen the following comments. I will look into this current sink system. For the incandescent lamp, I have considered it however since this project will later be used for teaching purposes I have been told it would be a problem if several units emitted 350W of light in a single lab...
Thank You for the quick response.
My knowledge of IGBTs is very limited. I have never used one and am not able to understand how it could be used to dissipate power.
Hi,
I'm currently working on my end of the year project for my studies.
I have a DC motor mechanically linked to a wind turbine PMA. My aim is to control the speed of this motor (using PWM) to simulate different types of winds.
My problem lies on the generator side. I need a load to...
