DC DC Converters

DC-DC converters are an important technology in maintaining power continuity in many electronics applications. DC-DC converters convert voltages and currents from a direct current (DC) source to a lower voltage, higher current, or both, and local load. This ability makes them an essential tool for powering a variety of AC and DC electronic devices.

VI-JWD-EX is one type of DC-DC converters which is widely used in various applications. The VI-JWD-EX application field can be seen by its function: it converts low voltage DC power to higher voltage DC power. It is suitable for applications that require a high voltage/current power supply such as medical, lighting, automotive and communication services.

The Working Principle of VI-JWD-EX

VI-JWD-EX is a switching mode power supply used to convert one DC voltage to another. It works by switching the input voltage through a power semiconductor, such as a transistor or a MOSFET. When the power semiconductor is activated, a controlled current flows to the output. The amount of current flowing from the input to the output is determined by the output voltage control and power specifications. The VI-JWD-EX has an integrated MOSFET which provides excellent efficiency and low heat dissipation. It also features active current control and short circuit protection.

In general, the VI-JWD-EX consists of two separate sections. The front end of the converter contains a power-switching circuit, and the transformer is connected to the power-switching circuit. The input voltage is supplied to the power-switching circuit and is rectified and smooth filtered to obtain a DC voltage, which is then stored in the associated capacitor. The power-switching circuit works by controlling the power supply switch, such as the MOSFET, according to the required output voltage.

The transformer is connected to the power-switching circuit and is responsible for converting the input voltages to control the output voltage. The output voltage is determined by the characteristics of the transformer and the input voltage. When the input voltage is supplied to the transformer, the ratio of the primary and secondary winding decides the output voltage. The output voltage is then rectified and filtered, and is supplied as the output voltage.

Conclusion

VI-JWD-EX DC-DC converters are an ideal choice for applications requiring a high voltage/current power supply. It can efficiently convert a low input voltage to a higher voltage, and it also has an integrated MOSFET for excellent efficiency and low heat dissipation. Furthermore, it features active current control and short circuit protection, allowing it to deliver reliable performance.
