Yes
"Bruce Raymond" wrote in message gy.com... I've seen the equation Po = V^2 / 2R applied to the design of Class C amplifiers. This doesn't make sense to me and I'm looking for corroboration, or somebody to tell me I'm an idiot ;-). The formula makes sense for a Class A amplifier which has conduction over 360 degrees, but would seem to overstate the power output for a Class C amplifier with, say a 120 degree conduction. An amplifier with a 120 degree conduction angle would only produce about 47% as much power as one with a 360 degree conduction angle (if I did the math right). Therefore, I'm assuming that the formula should be Po = .47 * V^2 / 2R, or Po = V^2 / 4.2R in this case. Is this correct? Thanks, Bruce Raymond/ND8I |
