Abstract
This paper presents the control strategies by Proportional-
Integral (P-I) and Fuzzy Logic (FL) for a DC-DC boost power converter
for high output voltage configuration. Standard DC-DC converters are
traditionally used for high voltage direct current (HVDC) power
transmission systems. But, lack its performances in terms of
efficiency, reduced transfer gain and increased cost with sensor
units. Moreover, the internal self-parasitic components reduce
the output voltage and efficiency of classical high voltage
converters (HVC). This investigation focused on extra highvoltage
(EHV) DC-DC boost power converter with inbuilt
voltage-lift technique and overcome the aforementioned
deficiencies. Further, the control strategy is adapted based on
proportional-integral (P-I) and fuzzy logic, closed-loop controller
to regulate the outputs and ensure the performances. Complete
hardware prototype of EHV converter is realized and
experimental tasks are set out with digital signal processor (DSP)
TMS320F2812 under different perturbation conditions. Observed
set of results is provided and shown good conformity with
developed hypothetical predictions.
