This book explains the basic theory behind transformers in the solar power arena and describes the development, manufacture, and sale of distributed photovoltaic grid transformers, which help boost the electric DC voltage harnessed by a photovoltaic panel to a higher level. Containing real-life scenarios, case studies from around the globe, and multiple homework questions, the text covers the key design, operation, and maintenance aspects of transformers suitable for solar energy, including islanding, voltage flicker, voltage operating range, frequency and power factor variation, and waveform distortion.
