A single-phase transformer is a transformer in which both the
primary winding and the secondary winding are single-phase
windings. Unipolar switching power supply means that the output is
unipolar, that is, only positive and negative output. Compared with
bipolar switching power supply, the bipolar switching power supply
has three outputs, which are divided into the positive power
supply, negative power supply, and ground wire. . Single-phase
transformers are simple in structure, small in size, and low in
loss, mainly due to small iron loss. They are suitable for
application and promotion in low-voltage distribution networks with
low load density. Suzhou City has used more than 1,000 units in
total, saving 45GWh of electricity, and the experience is worth
promoting. Some data show that single-phase transformers are widely
used in developed countries, such as the United States and Japan. A
Single-phase power supply is the main way to supply power to
residents. Under this propaganda, some people think that a
single-phase power supply has "loss reduction". The magic is that
single-phase transformers are more energy-efficient than
three-phase transformers and single-phase power supply systems are
superior to three-phase power supply systems. In fact, the
single-phase transformer and single-phase power supply system are
only supplementary forms of the current three-phase power supply
system. Due to its own characteristics, it can only be applied to
certain specific fields. "
