Öğe Power control of resonant converter MPPT by pulse density modulation(Institute of Electrical and Electronics Engineers Inc., 2017) Karafil, A.; Ozbay, H.; Oncu, S.This paper presents the simulation of series resonant converter system with proposed 32 pulse density modulation (PDM) patterns which transfer the electrical energy obtained from PV panels to load with high power density. Maximum power point tracking (MPPT) is achieved by deleting some control pulses. Therefore, zero current switching (ZCS) is achieved at 100 kHz resonant frequency. The average output power changes of series resonant converter are given according to the proposed 32 PDM patterns. Both the MPPT algorithm and the high frequency series resonant converter are controlled by TMS320F28335 DSP. In the 600 W PV system, soft switching condition is achieved by using the proposed 32 PDM technique. © 2017 EMO (Turkish Chamber of Electrical Enginners).
