I, What is power module?

The power module is a power converter that can be directly soldered to the circuit board. It is generally divided into AC to DC or DC to DC according to the conversion method. With the development of technology, the power supply volume tends to be modular and miniaturized, so power modules have emerged. Due to the electric eye module has highest integration degree, the main circuit of the switching power supply is integrated in the chip circuit, and functions such as wide frequency modulation, isolation, and other protections.

II, The basic principle of power module

（I）the input rectifier filter, including the rectifier bridge and the input filter capacitor. （II）Single-chip switching power supply, including power switch, controller and Mosfet. （III）.High frequency transformers, leakage clamp protection circuits, output rectifier filters, bias circuits and other components.

III, Power module advantages and applications

The power module has small size, high integration, high cost performance and best performance indicators. It only needs the simplest peripheral circuit and can be used with a small number of discrete components. It has the advantages of high efficiency, high reliability, flexible design, etc. It has become the preferred integrated circuit for developing and designing small and medium power switching power supplies.

As professional electronic transformer manufacturer, we produce and design various high frequency transformers, SMPS transformers, current transformers, flyback transformers to meet customers requirements. Our transformers are widely used in industrial control, mechanical equipment, shipbuilding, aerospace, communications, military, data communications, handheld electronic products, instrumentation, LED lighting, intelligent, electric power, railway, security, mining, medical, automotive electronics and other fields. .

The switching power supply transformer is a power transformer with a switching tube. In addition to the voltage conversion function of the ordinary transformer, the circuit also has the functions of insulation isolation and power transmission, which are generally used in switching power supplies and the like involving high frequency circuits. Recently, we produce EE13 /EE16 high frequency transformers for power module.
