Replacing fossil fuel-based energy with renewable energy has grown exponentially. Between different renewable energy generation techniques the solar photovoltaic (PV) technology is a superior solution especially for residential and small commercial renewable energy generation. Partial shading is one of the issues, which residential installations are facing. Photovoltaic module-level and sub-module-level power electronic systems could help addressing these issues by utilization а global maximum power point tracking (GMPPT) based on the I-V curve sweeping of the PV module. If properly implemented, the GMPPT would significantly enhance the shade tolerance of the PV installation up to the hard-shading scenarios, including the fallen leaves, bird droppings, or snow deposition on the surface of the PV module.

This seminar will review the shade-tolerant impedance-source PV microconverters, which address the partial shading issues of the residential and small commercial PV installations. The emerged approaches feature single- and multi-mode operation with wide input voltage and load regulation range along with capability of the global maximum power tracking down to very low input voltage values. One of the concepts, which was developed in cooperation with industrial partner will be introduced and discussed.
