Welcome to this channel. I make videos that delivers helpful information for my students considering the power electronics field or those who are looking for easy and enjoyable lectures to improve their skills.
Actually all you proven is that there are no even harmonics for this one case involving a highly inductive load and a full bridge rectifier. This does not consider other load cases. For example if you had the same highly inductive load and a half wave rectifier and ran the same analysis you will find that even harmonics do exist.
I have a basic question. Do this circuit only convert voltage unregulated for make the isolation purpose or do this circuit do both isolation and DC control regulation at the secondary side. Do this circuit need a second regulator for control the DC voltage level.
Thank you for this video. Could you do another video of implementing MPPT and PI controller to control output voltage of the boost converter using PLECS? Also how can a battery cell be modelled on PLECS?
This is how a traditional (not UcD) D-class amplifier with a full-bridge output stage works. Can be called an inverter if you like. However for 50/60Hz it's better to use a table with coefficients for a PWM in a microcontroller, rather then all these generators and comparators. Besides, a phase shift switching is simpler to implement with an MCU.
After some years not studying (because I started to work in the Industry) in the last months I decided to finish them. Getting back was rough but yesterday I aproved my penultimate Exam for graduating as Industrial Engineering. This videos helped me a lot getting back to this subjects. Great explanations. Thank you!
Your video is very helpful, but I have a question that, what duty cycle will you choose to generate drive pulse for mosfet, D =0.2 or D=0.8, hope you will answer soon. Thanks
Very useful video but do you have the last part of the video updated anywhere?.. I wanted to know about the control when we input the boost converter output as the control set point to the PI controller (as you talked about the change of gain of the controller according to the boost output)
thank you for such useful video! I have one question about how to choose mosfet for such DC-DC converter. Particularly I'm interested in such parameter of MOSFET as "Vds". So since we calculated our converter for output voltage 10v under load 10 Ohm, I assume that if we will disconnect the load, output voltage will start increasing. So it may damage mosfet if it will be much bigger than Vds parameter of MOSFET. So how to properly calculate DC-DC output voltage when load is not attached?
It depend, if you have negative feedback, the system will modify the duty cycle to stay at the same output voltage. If you don't have negative feedback, and a changing load, your output voltage will change, and if you remove the load, output voltage will increase, and destroy your MOSFET, your diode, and your capacitor.
