Lietojumprogramma of common mode induktivitāte in regulēta barošana padeve?
The common-mode inductor is essentially a two-way filter: on the one hand, it must filter out the common-mode electromagnetic interference on the signal line, and on other hand, it must restraint yourself from emitting electromagnetic interference to avoid influenceing the normal operation of other electronic devices in the same electromagnetic environment. . �% 80�
Common mode choke coils can transmit differential mode signals, both DC and low frequency differential mode signals can pass through, and present a large impedance to high frequency common mode noise, so it can be use to suppress common mode current disturbances.
Lietojumprogramma of common mode induktors in komutācija barošana padeve?
Parastais režīms induktori ir dažreiz saucas parastais-režīms drosele spoles, jo to funkcija ir to suppress, un tie ir galvenokārt lietoti in switching power supply circuits to form different filters to filters to filter EMI and suppress electromagnetic waves ģenerēts by dažādi ātrdarbīgi signāli no iet uz āru. Pārraide, as parādīts in the figure below, there is a group of parallel lines in the circuit, and the normal signal is basic neietekmē kad iet caur, bet kad tur ir a common mode current flowing through, due to the isotropy of the common mode current, a magnetic field in the same direction will be ģenerēts in the the coil. Increase the inductive reactance of the coil to make the spole eksponāts augsta pretestība un radīt a stiprs slāpēšana efekts. At šis laiks, the common mode current will be vājināts to sasniegt the purpose of suppressing interference.
1. Shematiska diagramma of the signāls caurbraukšana caurlaidība the common mode inductor
The schematic diagram of the front stage of the switching power supply, in which L1 is the common mode inductor. In order to suppress the common mode interference, we know that the common mode signal is a signal with equal amplitude and the same phase. For ground noise, if we understand the common mode noise, we will know the common mode inductor and why the common mode inductor is connected to the AC side.
