Charging electric vehicles (EVs) from photovoltaic panels (PV) provides a sustainable future for transportation. This paper presents the development of a 10 kW EV charger that can be powered from both a PV array and the three-phase ac grid. The goal is to realize a high power density and high-efficiency three-port power converter that integrates the EV, PV, and grid and meets the Chademo and combined charging standard/Combo EV charging standards. The EV port is designed to be isolated and bidirectional, so that both charging and vehicle-to-grid can be implemented. As PV and EV are both dc by nature, the converter uses a central dc link to exchange power between the EV and PV, thereby increasing efficiency. The use of silicon carbide devices and powdered alloy core inductors enables high switching frequency and power density. The closed-loop control allows four different power flows: <inline-formula><tex-math notation="LaTeX">${\text{PV}\rightarrow \text{EV}, \text{EV}\rightarrow }$</tex-math></inline-formula> grid, grid <inline-formula><tex-math notation="LaTeX">${\rightarrow \text{EV}}$</tex-math></inline-formula>, and <inline-formula><tex-math notation="LaTeX">${\text{PV}\rightarrow }$</tex-math></inline-formula> grid. Hence, the converter operates as a PV inverter, a bidirectional EV charger, and a combination of both. A 10 kW prototype has been successfully tested, and its experimental waveforms and measured efficiency are presented. It has three times the power density and higher partial and peak load efficiency when compared to existing solutions.
