Duality Theorem Juxtaposes Class-E and Inverse-Class-E Diode Rectifiers [Educator’s Corner]

Duality is an elegant and convenient way to create new electronic systems. Based on an existing system, we can effectively find out its counterpart by simply applying the duality theorem. The duality theorem works in a wide scope: not only for linear passive systems, but also for active, nonlinear, and even nonreciprocal systems.
