Abstract

In numerous applications, for example, substantial scale LCD board backdrop illumination, road lighting, burrow lighting, and so forth., an air conditioner / dc Light Emitting Diode (LED) driver ought to understand the accompanying three capacities at any rate: control figure adjustment, multichannel consistent ebb and flow yields, and galvanic disconnection. A novel two-arrange multichannel steady flow air conditioning / dc LED driver with a minimal effort and one of the model was proposed is made out of a high-recurrence resounding air conditioning / air conditioning converter and the same number of uninvolved LCL-T thunderous rectifiers as the quantity of the yield channels. To begin with, topology induction of the high-recurrence full air conditioning / air conditioning converter with single stage is introduced, additionally the working rule of it. At that point, the enduring state execution of it is totally dissected, including its info control calculate, voltage increase, add up to consonant twisting of its yield voltage, and its soft switching condition. In order to generate the pulses for MOSFET PWM techniques and PI controller model is also developed to eliminate steady state error. Here both open loop, closed loop and fuzzy control of high frequency single stage resonant AC to AC converter model is developed using MATLAB / SIMULINK software.

Keywords: Fuzzy logic control, Open loop and closed control, Resonant converter.
