Better protection switching power supply provides a very good condition

Switching power supply has several decades of development history, since the late 1970s, with the development of modern power electronics technology, there has been a lot of excellent  air circuit breaker  and high power devices and integrated, powerful companion chip, which is developed a high efficiency , small size, light weight, easy to control, and better protection switching power supply provides a very good  electric meter . Early general use of the excimer laser resonant charging power for tens of thousands of volts to charge the energy storage capacitor, and  power transformers the thyratron gas discharge excitation and thus the light. Such power generally frequency transformers, large storage capacitor.
