Wow, where is the best place to get info on the D and E class amps? --Original Message-- From: [email protected] [mailto:[email protected]]On Behalf Of Dexter McInty
Hello Mal, with my 136kHz PA (variant of the G3YXM Class-D push-pull) I get 450W output with 56V/9.5A supply, thus 85% efficiency. I once tried a 50W class-E PA and got over 90% efficiency with corre
These articles have the information you need to design and tune a class E amplifier: http://www.arrl.org/tis/info/pdf/010102qex009.pdf http://www.cs.berkeley.edu/~culler/AIIT/papers/radio/Sokal%20AAC
Thank you, I will take a look. de kd4wov These articles have the information you need to design and tune a class E amplifier: http://www.arrl.org/tis/info/pdf/010102qex009.pdf http://www.cs.berkeley.
Class E ( and I think also probably Class D but I am not sure about that one) will only give maximum efficiency at the design power loading. You cannot tune for max smoke (well you can if you have di
Hi all Class D and E amplifiers are supposed to give around 80/90 % efficiency. Has anyone actually achieved these figures. It seems anything above 60% is hard to arrive at using normal coils/capacit
Hello Mal & LF, The best I've acheived with Class-E has been about 70-75%. I understand that you're supposed to select values of components and tune the o/p stage for best efficiency at your chosen D
