What is the power module?

The power module is actually a directly welded to the circuit board of the power conversion assembly. With the development of science and technology, the volume of power supply tends to be modular and miniaturized, so the emergence of power module. Its highest integration, the main circuit of the switching power supply integrated in the chip circuit, can realize the wide frequency modulation, isolation and a variety of protection and other functions.

The main function of power module is to convert alternating current and direct current to each other. According to the conversion mode, it can be divided into AC-DC and DC-DC two modes, which can provide power for ASIC, digital signal processor, microprocessor, memory, field programmable gate array and other digital or analog loads.

The common rationale consists of the following parts, the input rectifier filter, including the rectifier bridge and the input filter capacitor. Monolithic switching power supply comprises power switching tube, controller and MOSFET. There are high frequency transformer, leakage level clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts.

The 3W wide voltage isolation power module produced by the YLZ has:

1. Compact and flexible design, convenient and fast maintenance

2. Save cost and time

3. High power, high efficiency and high stability

The above advantages make it favored by users in many industries, especially in the exchange access equipment, mobile communication, microwave and other communication fields and automotive electronics, aerospace and other industries are widely used. Therefore, it is widely used in industrial control, mechanical equipment, ships, aerospace, communications, military, data communication, handheld electronic products, instruments and meters, LED lighting, intelligent, electric power, railway, security, mining, medical, automotive electronics and other fields.
