#98493 - Re: No Match.
Responding to: Steve M. Taylor's previous message
Dear Steve,

Thanks for your reply,


Why do you want to load match ?

For Maximum Power Transfer from Source to Load at high frequencies 300Hz - 200KHz.


If you have control of the source impedance, you want 0 output impedance.

How can I control the source impedence of a MOSFET or IGBT full/half H Bridge. AFAIK it is Voltage rating / Operating current.


You do NOT want to match the load.


I visited many websites such as this http://www.richieburnett.co.uk/indheat.html and all such websites talk about impedence matching between load tank circuit and the IGBT H bridge some suggest LC Match others suggest HF transformers.

Please provide me some more help with this.

Thanks & Regards,
Prahlad Purohit
