There is usually no problem with the input source and output load current loops. The current waveforms in these loops are a superposition of large DC currents and small AC currents. Special filters are usually required in these two circuits to prevent AC noise from leaking into the surrounding environment. The input and output current loops obtained from AC/DC Power Supply PCB Board Cloning should be connected to the power supply only from the terminals of the filter capacitor.
The input loop charges the input capacitor with an approximately DC current, but does not provide the high frequency current pulses required to switch the ac/dc power supply. The filter capacitor mainly acts as a broadband energy storage; similarly, the output filter capacitor is also used to store the high frequency energy from the output rectifier while eliminating the DC energy of the output load loop only after the process of REVERSE ENGINEERING PCB BOARD GERBER FILE PRECAUTION.
Therefore, the terminals of the input and output filter capacitors are very important. If the connection between the input/output loop and the power switch/rectifier loop cannot be directly connected to the capacitor terminal, the AC energy will “flow through” the input or output filter capacitor. And radiate into the environment.
The current waveforms of the two basic PWM modes of operation produce harmonic current waveforms that are much higher than the switching frequency which becomes critical for AC/DC Power Supply PCB Board Cloning.
The AC circuit of the power switch and rectifier contains a high amplitude trapezoidal current waveform. The harmonic content of these waveforms is very high, and its frequency is much larger than the fundamental frequency of the switch. The peak amplitude of these AC currents can be up to 5 times the amplitude of the continuous input/output DC current in the process of REVERSE ENGINEERING CIRCUIT CARD POWER & GROUND, and the transition time is usually about 50 ns. These two loops are the easiest to generate. Electromagnetic interference.
