Buck-Boost Converter Efficiency Maximization via a Nonlinear Digital Control Mapping for Adaptive Effective Switching Frequency

A nonlinear control loop mapping has previously been designed for mitigating the dead zone of a noninverting buck-boost converter while minimizing state variable perturbation. This paper derives a new nonlinearity that enables a converter with fixed switching frequency to achieve reduced switching l...
