Hloov Kev Paub Txog Kev Siv Hluav Taws Xob

Lub ntsiab lus ntawm kev hloov hluav taws xob: hloov hluav taws xob hloov hluav taws xob (Switching Power Supply), kom muaj kev ruaj ntseg ntawm cov zis hluav taws xob los ntawm kev tswj xyuas qhov sib piv ntawm cov raj hloov, me me, lub teeb yuag (20 mus rau 30% ntawm qhov ntim thiab qhov hnyav ntawm cov linear fais fab mov), efficiency siab (feem ntau 60 mus rau 70%, thiab linear fais fab mov tsuas yog 30 mus rau 40%), muaj zog tiv thaiv kev cuam tshuam, dav tso zis voltage ntau, thiab modular. Cov yam ntxwv ntawm kev siv hluav taws xob tsawg, me me ripple, tsis tshua muaj suab nrov, thiab kev nthuav dav yooj yim ua rau lub zog hloov hluav taws xob muaj kev ruaj ntseg thiab kev ua haujlwm zoo, thiab tau siv dav hauv cov twj paj nruag, meters, industrial automation thiab lwm yam.

Tshawb nrhiav lub hom phiaj ntawm kev hloov regulators:

1. Fais fab hloov dua siab tshiab efficiency

2. Bulk density power ratio

3. Tawm tswv yim thiab tso zis voltage tswj cov teebmeem

4. Tso tawm luv luv Circuit Court thiab tiv thaiv tam sim no

5. Siv ib puag ncig thiab qhov kub thiab txias qhov yuav tsum tau ua

6. EMI thiab RFI tsis

7. Lub neej thiab lub zog hloov lub sijhawm

8. Tus nqi sib tw

Txoj kev los txhim kho efficiency:

1. Ntxiv ib qho passive lossless absorption Circuit Court rau DC-DC tso zis seem.

2. Siv Schottky rectifier diode hloov ceev rov qab diode.

3. Xaiv cov zaus ua haujlwm tsim nyog.

4. Cov qauv tam sim no siv lub resistor nrog me me tsis kam.

5. Lub voltage tswj hom Circuit Court raug xaiv, thiab tam sim no sampling resistor raug rho tawm.

6. Lub raj hloov hluav taws xob siv lub tshuab hluav taws xob qis qis MOS.
