DC DC Converters

DC-DC converters are electrical power conversion devices that are used to efficiently convert electrical energy between two different voltages. They are designed to supply and adjust the voltage of different loads while maintaining the energy efficiency of the system.

The PQB3-D5-D5-D is a DC-DC converter from Artesyn Embedded Technologies. It is a high-precision, wide operating range power supply specifically designed for space and aviation applications. It has been certified to meet many safety requirements, including commercial-ground and air safety standards.

The PQB3-D5-D5-D is a four-stage DC-DC converter featuring a wide input voltage range of 10.8 VDC to 36 VDC and an adjustable output voltage of 0.2 VDC to 28 VDC. It has a power capability of up to 1500 W and offers high-precision regulation. The device provides fault protection and current limiting with alarm signals. It also features active equalization, which ensures proper input voltage sensing and output load control, along with transient protection.

The PQB3-D5-D5-D works by converting incoming DC power from the input to a specific output voltage range, while maintaining high efficiency. This is achieved by using a four-stage conversion process. The four stages consist of: input stage, primary conversion stage, secondary conversion stage, and output stage. In the input stage, the device receives the incoming input voltage and converts it to a regulated intermediate voltage level. The primary converter stage then further converts the intermediate voltage to an even more regulated voltage. This regulated voltage is then further converted to the desired output voltage level in the secondary conversion stage. Finally, the output stage regulates the output voltage to the desired output voltage level.

The components used in the PQB3-D5-D5-D are made from high-grade materials and designed to withstand high temperature and power fluctuations. The device accepts power from both AC and DC sources and is designed to meet the most rigorous industry requirements. It is specifically designed for applications in aerospace, defense, and automotive industries, as well as in industrial and medical settings.

The PQB3-D5-D5-D is a reliable and efficient power conversion device, capable of operating in tough environmental conditions. It provides outstanding electrical characteristics, along with protection features, high power flexibility, and wide operating temperature range. This makes it ideal for high-end applications that require an efficient and reliable power solution.
