ABSTRACT: Boost-Buck converter
is widely used in LED lighting drivers. In this paper, Boost-Buck main circuit
related characteristics are firstly discussed, and then a new Boost-Buck high
power efficient double loop control strategy is built by adopting error
amplifier and integrator control method. It is demonstrated that the new system
has many advantages such as high efficiency, fast response, strong
anti-interference, good stability after analyses and simulations of its working
dynamic characteristics.
