Ready to get your black belt in DC power conversion? In this episode of Chalk Talk, Amelia Dalton chats with Sam Abdel-Rahman of Infineon about how to make a versatile, high-efficiency, LLC resonant mode power converter. So, buckle up, hit play, and get your DC on!

Great Video.In 9:22, Sam mentioned that in the capacitive region the current is lagging the voltage, but it should be the current is leading the voltage.

Raed Mohsen yeah it's kind of confusing

@ameerjanabi917 5 жыл бұрын

at the capacitive, the current is leading (hard switching). At the inductive region the current is lagging (ZVS). This guy got it wrong.

I was going to comment but you already did.

in9:22 till 9:51 Sam just conflicted between ZVS and ZCS. The right is where tank current lags the impressed voltage is therefore called the "inductive region" and ZVS occurs, vice versa.

Thanks so much this wonderful, I have question about DC-DC bidirectional ,primary side and secondary side is full bridge how can I turn on with minimum losses to achieve high efficiency

W-a-i-t a minute! 1:54 to 2:00==> Is this LCC or LLC? There is a big difference!

Is there any application note for calculating the efficiency of the converter with different input voltages(for wide voltage range as input)

How can I design the LLC power supply with variable output DC voltage keeping the hardware same.The C voltage should vary from 60V to 350 volts.Can I do pulse skipping to reduce the voltage?

Sir, at 9:18 , you say in the capacitive region, current lags behind the voltage. and in inductive region, current leads the voltage. How is that possible? Please clarify it.

Yeah, I was wondering about this too. Seems backwards to me.

You should be able to do something by changing the switching frequency and may be try to change FETs duty cycle
