摘要：
A transformer having input and output windings. A sample transformer includes an input winding wound around a core. The input winding has a first end and a second end. An output winding is also wound around the core. The output winding has a first end and a second end. The input winding is capacitively coupled to the output winding to provide a transfer of energy from the input winding to the output winding. A balancing winding is also wound around the core. The balancing winding has a first end and a second end. The first end of the balancing winding is electrically coupled to the first end of the input winding. The second end of the balancing winding is uncoupled such that a dot polarity of the balancing winding is to oppose an electrostatic field to be generated by the input winding relative to the output winding.
