High-frequency link technology has the advantages of high power density, high reliability and electrical isolation. With the development of modern power electronic technology, highlighting its potential advantages, the development of new energy electric vehicle technology is also expanding its application field. A kind of brushless DC motor (BLDCM) driver for electric vehicle containing high frequency...
The traditional AC-DC power switching supplies often use the diode rectifier, due to the presence of the large filter capacitor and the switching devices, the power factor of the circuit is usually low, and the harmonic pollution in the grid side is serious. To solve the problem, a method that cascades a PFC (power factor correction) circuit is generally used, however, this increases the circuit stages,...
