Resumen
Boost dc–ac inverter naturally generates in a single
stage an ac voltage whose peak value can be lower or greater than
the dc input voltage. The main drawback of this structure deals

Boost dc–ac inverter naturally generates in a single
stage an ac voltage whose peak value can be lower or greater than
the dc input voltage. The main drawback of this structure deals
with its control. Boost inverter consists of Boost dc–dc converters
that have to be controlled in a variable-operation point condition.
The sliding mode control has been proposed as an option. However, it does not directly control the inductance averaged-current.
This paper proposes a control strategy for the Boost inverter in
which each Boost is controlled by means of a double-loop regulation scheme that consists of a new inductor current control inner
loop and an also new output voltage control outer loop. These loops
include compensations in order to cope with the Boost variable operation point condition and to achieve a high robustness to both
input voltage and output current disturbances. As shown by simulation and prototype experimental results, the proposed control
strategy achieves a very high reliable performance, even in difficult
transient situations such as nonlinear loads, abrupt load changes,
short circuits, etc., which sliding mode control cannot cope with. [--]
