12SE-100 Application Field and Working Principle

12SE-100 is an a kind of accessory in the field of electronic products, which is widely used in current electronic devices. It is a high frequency switching power supply for switching DC/DC power conversion applications. It adopts synchronous rectification mode, and has superior performance compared with traditional switching power supply.

Principle of Operation

The 12SE-100 circuit includes a rectifier, a filter, a transformer, an inverter and other electronic components. The rectifier module converts the AC voltage into DC voltage. In the inverter module, a PWM (Pulse Width Modulation) module is used to control the duty cycle. The PWM module switches the electrical energy stored in the inductor between different frequencies and current levels, while the transformer changes one frequency of alternating current to another frequency. The output of the transformer is rectified by a diode bridge, then filtered through capacitors.

The whole circuit has some common components, such as an input rectifier, an inverter, an output filter, and a control circuit, which are closely related. The controlled switch is the core part of the switching circuit. The control circuit converts the input signal to a PWM signal, which drives the switching circuit. The switching circuit conducts alternately according to the PWM signal, and the output voltage of the DC-DC converter is equal to the input voltage multiplied by the duty cycle. The output voltage is then smoothed by the output filter.

Application Fields

12SE-100 is mainly used in automotive applications for achieving high frequency switching and power conversion, such as power steering, braking system, etc. It can also be used in mobile phones, tablets and other mobile devices. Moreover, it can be applied to LED lighting, communications, and electronic tools. In medical equipment, 12SE-100 also can be used in defibrillator, CT scan and MRI, etc.

Conclusion

12SE-100 is a high frequency switching power supply, which is widely used in current electronic devices. The whole circuit includes a rectifier, a filter, a transformer, an inverter and other electronic components. 12SE-100 can be applied in automotive and medical equipment, as well as for mobile devices, LED lighting, communications, and electronic tools.
