This paper proposes the design and co-simulation of a Solar-Powered Wireless Electric Vehicle (EV) Charger employing a Pulse Density Modulation (PDM) controlled Maximum Power Point Tracking (MPPT) algorithm for enhanced efficiency and precise power flow management. The system is engineered to efficiently harvest energy from a high-power Photovoltaic (PV) array and transfer it wirelessly to an EV battery. The entire power stage, which includes the PV array, Series Resonant Inverter, Wireless Power Transfer (WPT) coils, rectifier, and battery load, is modeled in PSIM. Conversely, the Perturb and Observe (P&O) MPPT algorithm and the generation of the control signals via a 16-level Irregular PDM technique are implemented in MATLAB/Simulink using a co-simulation methodology. The system was tested under varying solar irradiance levels. Results confirm the PV array's maximum power was successfully tracked, while the 16-level Irregular PDM control method ensured precise power flow regulation. Crucially, the PDM strategy facilitated reliable Zero Voltage Switching (ZVS) operation, which is key to guaranteeing the high overall efficiency of the wireless charging process.

Bu çalışma, yüksek verimlilik ve hassas güç akış yönetimi için Darbe Yoğunluk Modülasyonu (PDM) kontrollü Maksimum Güç Noktası Takibi (MPPT) algoritması kullanan, Güneş Enerjili Kablosuz Elektrikli Araç (EA) Şarj Sistemi tasarımını ve ve bu sistemin benzetim sonuçlarını sunmaktadır. Sistem, yüksek güçlü Fotovoltaik (FV) dizisinden enerjiyi verimli bir şekilde elde etmek ve bu enerjiyi kablosuz olarak bir EA bataryasına aktarmak üzere tasarlanmıştır. FV dizisi, seri rezonans invertör, kablosuz güç transferi bobinleri, doğrultucu ve batarya yükünü içeren tüm güç aşaması PSIM yazılımında modellenmiştir. Buna karşın, Perturb and Observe (P&O) MPPT algoritması ve kontrol sinyallerinin 16 seviyeli Düzensiz PDM tekniğiyle üretimi, ortak-simülasyon metodolojisi kullanılarak MATLAB/Simulink'te gerçekleştirilmiştir. Sistem, değişen güneş ışınım seviyeleri altında test edilmiştir. Sonuçlar, FV dizisinin maksimum gücünün başarıyla takip edildiğini doğrulamakta, aynı zamanda 16 seviyeli Düzensiz PDM kontrol yönteminin hassas güç akışı regülasyonunu sağladığını göstermektedir. PDM stratejisi, kablosuz şarj sürecinin yüksek verimliliğini sağlayan ve anahtar unsur olan Sıfır Gerilim Anahtarlama (ZVS) operasyonunu mümkün kılmıştır.
