Is a precision rectifier more effecient than a syncronous rectifier? Ie, what actually is the power dissipation of an ideal diode?? And is it designed to dissipate less power than an SR typically?
In the case of an X-rated capacitor, is power dissipation equivalent to the [V^2 ÷ ESR], or [V^2 ÷ Capacitive resistance]?
Why can't you PWM a full bridge with a power MOSFET? Is phase angle control more effecient? Zero point switching only has to turn components on twice per period, while PWM-ing a full bridge output would require a higher freq of switching compared to diac+triac, which in turn draws more power?
How about a combination of different types of V regulation? ...
(Phase angle control) + (SCR) ?
(Transformer) + (phase angle control) ?
Interested in finding an effecient way to variably regulate voltage. Power dissipation generally goes up with lower load requirements and looking to learn and understand the ~% of power dissipated in various techniques of rectification and voltage regulation. I don't have a cct or schematic I'm currently working on, just looking to acquire knowledge to further my understanding. Thanks.
