The topology diagram of switching power supply is ever-changing, but no matter how it changes, it is basically based on the combination or deformation of basic topology diagram of switching power supply. There are basically 14 basic topology diagrams of basic switching power supply, so let's introduce them.



二、Basic pulse width modulation waveform of
     
These topologies are all related to switching circuits, and the basic pulse width modulation waveform is defined as follows:  
   
 



八、Two-Transistor Forward
     
 
   
  Features: ■ Two switches work at the same time. ■ When the switch is off, the energy stored in the transformer reverses the polarity of the primary and turns on the diode. Main advantages: ■ The voltage on each switch will never exceed the input voltage.■ There is no need to reset the winding track.

These are the common switching power supply topologies, and there are many topologies, but most of them are combinations or variations of the topologies described here. Each topology contains unique design trade-offs, and Sacco Wei has also done some sorting, which will be shared with you one after another in the future.



In recent years, SAKO Micro Semiconductor slkor (www.slkormicro.com) has developed rapidly. While consolidating its position in the power device market, it has laid out TVS transient suppression diode, driver IC, power management IC, AC-DC, LDO, Hall electromagnetic sensor, etc., and formed an ecological chain with SLKOR power devices for coordinated development. Sawei slkor's domestic alternative products can include many international famous brands such as DIODES Meitai, Vishay Weishi, TI Dezhou Instruments, ON Anson Mei, NXP NXP, IR International Rectifier, etc. Sawei Semiconductor Driver IC(SL8402) can replace ON ANSSENMEI NCV8402. After testing, all parameters have reached the specified indexes, and its stability is inferior to that of the same type products of TI Texas Instruments. In addiTIon, SLKOR micro-drive IC(SL27523) replaces ti Texas instruments UCC27523, SLKOR micro-linear voltage regulator SL42744D replaces IR international rectifier TLE42744D, and SLKOR micro-linear voltage regulator SL4264-2 replaces IR international rectifier TLE4264-2. SLKOR micro hall sensor SLSS341R replaces Honeywell SS341R, SLKOR micro hall sensor SLSS451A replaces Honeywell SS451A, SLKOR micro SL2044 (power management IC) replaces Atmel Termel U2044, and SLKOR micro power electronic switch SL3405G replaces IR international rectifier BTS3405G.
