TEQ 200-4818WIR

DC-DC converters are a specialized type of power supply that utilizes solid-state electronics to convert a direct current (DC) input voltage to a different output voltage and current, without the need for mechanical components. TEQ200-4818WIR is a type of DC-DC converter designed for use in applications that require a wide input voltage range and heightened electrical isolation. This article will present an overview of the TEQ200-4818WIR application field and working principle.

Application Field of TEQ200-4818WIR

The primary application field for the TEQ200-4818WIR, is in photovoltaics, or solar power generation. Specifically, it can be used for solar power supply systems, where the input voltage is provided by a solar power panel, and is typically 11-18V DC. It can provide an isolated output voltage of up to 48V DC, making it ideal for powering residential and commercial solar power-generating systems. It also provides a wide input voltage range, from 10V to 120V DC, enabling it to be used in a variety of other applications where a wide range of input voltages may be encountered.

The TEQ200-4818WIR also has a high Power Factor Correction (PFC) rating, which is important for the efficient operation of solar power systems. PFC is a measure of the power draw of the device relative to its output power draw. A high PFC rating means that the TEQ200-4818WIR is able to convert a larger amount of input power into usable output power, resulting in a greater efficiency of the solar power system.

Working Principle of TEQ200-4818WIR

At the heart of the TEQ200-4818WIR\'s working principle is its buck-boost converter. A buck-boost converter is an electronic device that combines a voltage regulator and two opposite-polarity transistors (the buck converter and the boost converter). This allows the device to convert a given DC input voltage, to a different output voltage without changing the input-to-output power ratio. The device also has a high-frequency transformer added to it for isolated power conversion and galvanic isolation. The TEQ200-4818WIR\'s transformer is relatively small for its application field, which is an important factor in achieving a high power efficiency for solar power systems.

The buck-boost converter works by using a combination of a buck converter and a boost converter. When the input voltage is lower than the required output voltage, the buck-converter converts the input voltage into a higher voltage, and the boost-converter follows, thereby converting the higher voltage into the required output voltage. Conversely, when the input voltage is higher than the required output voltage, the buck-converter will convert the higher voltage to a lower voltage, and then the boost-converter will follow, converting the lower voltage into the required output voltage.

Conclusion

The TEQ200-4818WIR is a DC-DC converter with a wide input voltage range and a high power efficiency. It is ideally suited for solar power systems, where it can be used to convert the input voltage into an isolated output voltage of up to 48V. The device works by using a combination of a buck converter and a boost converter, with a high-frequency transformer for isolated power conversion and galvanic isolation. This makes it possible to achieve a high power efficiency for solar power systems.
