Hi!. It's quite common to see the LCL (series L, parallel C and L) topology after the output transistors in DIY literature. This calls for few turns on the working inductor, of high diameter water cooled copper tubing, with parallel capacitors.
Instead, I designed my 50kHz 1kW prototype heater with a simple series LC configuration, this way the inductor has more turns of thinner wire thus having less skin effect, so it has higher Q, and does away with losses on the first (matching) inductor.
Can anybody tell me why this simpler topology is almost never used?.
Thanks!
