The power exchange inherent voltage techniques and power electronics skills transformation technique is a "typical" electronic transformer can low pressure into the low-voltage step-up transformation.

Low-voltage to low voltage step-down transformation, an important way is to take power electronics skills to progress in the power conversion frequency, thereby reducing the size of the circuit in the transformer and inductor, not to ban the transformer and inductor. Previously such a way to unite the power electronic circuits and electronic Isolation Transformer, did not cause enough focus on.

In recent years, with the power system request additional output and output harmonics, progressive line-side power factor, "green transformation" has become increasingly depressed at home and abroad launched a study of power electronic transformer ", before the decline of research development boom. To study how the electricity power electronics skills to transform and master alternative to conventional electromagnetic type distribution transformers with power electronic transformer.

Now has a single phase transform and three-phase transformation a variety of circuit situation, this power Electrical Transformer Qidan for low-voltage high-current power areas, can be used for low voltage or low voltage low current areas, such as low-voltage power attack and power regulator power supply.

Engaged in electronic transformers to study development for production units has exceeded 2000, including public, private and foreign companies. The world's largest electronic transformer consumer manufacturers Pulse, and the world's largest consumer of soft ferrite manufacturers in Japan TDK Corporation has a consumer base in China. The world's many advanced electronic transformer skills, consumer technology and products in our country together. Faced with a multiple of platforms, skills exchange is promising.
