Hitek power supply maintenance X-ray machine high voltage generator maintenance xr150-603-02

High voltage power supply maintenance includes splashing power supply maintenance 、RF RF power supply 、 Various AC and DC industrial power supply maintenance , The brands are German singulus、MKS、eni、 The United States AE、M2、ADVANCED ENERGY、RFPP、KYOSAN、ADTEC、COMDEL、HUTTINGER、ADL、KIKUSUI、 Japanese chrysanthemum water, etc .

 

Switch triode and switch transformer are the main components of switching power supply , The switch is operated at saturation by self-excited or other excited mode 、 end （ Instant on 、 Turn off ） state , Thus, a high-frequency voltage is induced on the secondary winding of the switching transformer , After rectification 、 Various DC voltages are output after filtering and voltage stabilization . Quality directly affects the quality and service life of power supply .

Especially switch three and tube , Working under high back pressure , There is not enough protection circuit , It is easy to puncture and burn . The factors that affect the performance of high frequency switching transformer include the efficiency of ferrite 、 The size of the cross-sectional area of the magnetic core and the width of the magnetic attraction , The transformer with too small cross-sectional area is easy to produce magnetic saturation and cannot output large power , The number of turns of each winding directly affects the output voltage , Usually we can't grasp these parameters .

The development and application of power supply is to save energy 、 Saving resources and protecting the environment are of great significance . Switching power supply can be divided into AC/DC and DC/DC Two categories: ,DC/DC The converter is now modular , And the design and production process have been mature and standardized in , And has been affirmed by users , but AC/DC The modular , Because of its own characteristics, in the process of modularization , Encounter more complex process and manufacturing problems .

 

People are edge related power electronic devices in the field of switching power supply , Side switch frequency conversion , The two mutually promote the switching power supply to become lighter with the growth rate of more than two digits every year 、 Small 、 thin 、 Low noise 、 The direction of anti .

Switch tube and switch transformer ： As the name suggests, switching power supply is the word switch . Switch tube and switch transformer are components of switching power supply , The switch is operated at saturation by self-excited or other excited mode 、 end （ Instant on 、 Turn off ） state , Thus, a high-frequency voltage is induced on the secondary winding of the switching transformer , After rectification 、 Various DC voltages are output after filtering and voltage stabilization . Switch tubes and switch transformers are ATX Power supply components , Its quality directly affects the quality and service life of the power supply . Especially the switch tube , Working under high back pressure , There is not enough protection circuit , It is easy to puncture and burn .

The factors that affect the performance of high frequency switching transformer include the efficiency of ferrite 、 The size of the cross-sectional area of the magnetic core and the width of the magnetic gap , The transformer with too small cross-sectional area is easy to produce magnetic saturation and cannot output large power , The number of turns of each winding directly affects the output voltage , Usually we can't grasp these parameters .
