New results on the energy-based control of series resonant inverters

摘要

In a recent work the author presented a hybrid control scheme for series resonant inverters owning a number of nice properties. In the present work several refinements and bounds on the allowable parameters are obtained yielding a more precise methodology to design the hybrid control scheme presented in the previos work. In particular we define the permissible range of loads and controller gains, we present a complete proof for asymptotic stability when the hybrid control strategy is used and we ensure that no catastrophic failure occurs when a zero resistance is used as load. Another important new feature in this note is that results do not require the exact knowledge of any of the plant parameters.
