The reliability problems and advantages of coreless printed circuit board transformers for application are described. The coreless PCB transformers eliminate the limitation associated with magnetic cores for the frequency, magnetic saturation and core losses. Their parameters can be precisely controlled by using modern PCB technology and they can be easily manufactured in a large scale. They are mainly applied in converting of energy and signals and have great application potentials.
