Wall Adapter Near Me

With all the certifications UL, ETL, FCC, CE, CB, GS, CCC, CQC, PSE, KC, KCC, SAA, RCM, etc.

With the development of power supply technology, now, electronic instruments and equipment in the performance of more secure and reliable, functionality is constantly enhanced, the use of automation is also increasingly high. And these electronic technologies and their applications continue to develop can not be separated from the power adapter, power adapter in the computer, communications, aerospace, home appliances, etc. have been more and more widely used, the type of power adapter is also more and more. Today Eahunt power supply manufacturers will simply for you under the inventory, what are the classifications of adapters?

1, according to the modulation mode classification

① Pulse width modulation type switching regulated power adapter. Oscillation frequency remains constant, by changing the pulse width to change and regulate the size of the output voltage, sometimes through sampling circuits, coupling circuits, etc. constitute a feedback closed-loop loop to stabilize the amplitude of the output voltage.

② Frequency modulation type switching regulated power supply adapter. Duty cycle remains unchanged, the amplitude of the output voltage is regulated and stabilized by changing the oscillation frequency of the oscillator.

③ Hybrid modulation type switching regulated power supply adapter. By adjusting the on-time oscillation frequency to complete the regulation and stabilize the amplitude of the output voltage.

2, according to the excitation mode classification

He excitation type switching regulated power supply adapter. There is an oscillator in the circuit to stimulate the signal.

② self-excited switching regulated power supply adapter. The switching tube doubles as the oscillator in the oscillator.

3、Categorized by circuit structure

① Bulk type switching regulated power supply adapter. The entire switching regulator power adapter circuit is composed of discrete components, its structure is more complex, less reliable.

② integrated circuit type switching regulated power adapter. The entire switching regulated power adapter circuit or part of the circuit is composed of integrated circuits, this integrated circuit is usually a thick film circuit. Some thick film integrated circuits include switching tubes, and some do not include switching tubes. This type of switching power adapter is characterized by a simple circuit structure, easy debugging, and high reliability.
