摘要: This paper presents the implementation of a digital phase-lead plus resonant controller for photovoltaic (PV) applications using delta operator in low-cost 16 bit fixed-point controller. The is used to reduce low frequency voltage ripple across PV array step-up dc-dc converter grid-connected applications. Delta proposed solve problems related imprecise parameters representation conventional shift implementation. Simulation and experimental results operators are presented demonstrate advantages form.
