The work is dealing with the problem of developing an embedded system for supply voltage converter of Organic Light-Emitting Diode (OLED) with advanced functionality, namely - with an embedded ability to measure the Volt-Ampere (V – A) characteristics of structures directly during their operation. The measurement of the V – A characteristics of OLED structures is performed on the transient processes of voltage generation in the drivers boost circuits. Model researches show the operating conditions of the boost OLED power driver with in-situ measurement of its V – A characteristics. In accordance with the results of model researches and requirements for the implementation of modern electronics devices, an embedded system of voltage converter for OLED structure has been developed. The basis of the developed converter is a programmable system on chip PSoC of 5LP Family Cypress Semiconductor Corporation.

Praca dotyczy problemu opracowania wbudowanego systemu przetwornika napięcia zasilania organicznej diody elektroluminescencyjnej (OLED) z zaawansowaną funkcjonalnością, mianowicie - z wbudowaną możliwością bezpośredniego pomiaru charakterystyk woltoamperowych (W – A) struktur. podczas ich eksploatacji. Pomiar charakterystyki W – A struktur OLED wykonywany jest na przejściowych procesach generowania napięcia w obwodach doładowania sterowników. Badania modelowe pokazują warunki pracy zasilacza boost OLED z pomiarem in-situ jego charakterystyk W – A. Zgodnie z wynikami badań modelowych oraz wymaganiami dla implementacji nowoczesnych urządzeń elektronicznych, opracowano wbudowany system przetwornika napięcia dla struktury OLED. Podstawą opracowanego konwertera jest układ programowalny na chipie rodziny PSoC 5LP Cypress Semiconductor Corporation.
