Two issues pertinent to magamp post regu lator are treated in this thesis.
One of the issues considered is the operation of a magamp under extreme loading conditions. Practical design equations are derived to allow magamp operation under extreme load conditions such as shutdown of output, foldback of output current and very light load (discontinuous operation).
The other issue considered concerns with magamp post regu lation for a quasiresonant converter. A magamp circuit is proposed, designed and tested for a zero current switching quasi-resonant forward converter. It demonstrates that output regulation in a quasi-resonant converter can be achieved with a fixed switching frequency operation. It also demonstrates the feasibility of multiple regulated output application of a quasi-resonant converter.
