DC DC Converters

As a type of power converter, DC-DC (Direct Current - Direct Current) also known as a DC power converter, is a device used to convert one form of DC energy to another. It can convert electric power from one voltage to another, or one current to another. DC-DC converters can be used for many applications, including automotive, aerospace, communications, energy harvesting, entertainment, medical, industrial, and military.

One such DC-DC converter is the REC 3-4809SRWZ/H6/A/M, which is an isolated half-bridge DC-DC converter with high efficiency and low standby power.

Application Field

The REC 3-4809SRWZ/H6/A/M is primarily used in high-power applications such as motor-drive applications for electric vehicles, avionics, battery-charging systems, and LED lighting systems. Its low standby power and high efficiency allow for the device to be used in a wide range of applications, including energy harvesting, industrial, automotive, and communications. Its isolated configuration also allows for safe operation in hazardous environments.

Working Principle

The REC 3-4809SRWZ/H6/A/M features a half-bridge, series-mode connection, which allows for a lower standing power and higher efficiency than more simple topologies. The series-mode configuration also offers fast transient response for applications that require rapid output voltage adjustments. The isolation between input and output is achieved via the use of an optically-coupled transformer, a type of transformer that does not require the input and output to be connected. This ensures a high degree of safety and performance from the device.

The device is designed with overload and short-circuit protection, temperature protection, and under-voltage protection. This ensures that the device is able to withstand a wide range of operating conditions without damage. In addition, the device has a wide input voltage range, allowing for flexibility in design and application.

The REC 3-4809SRWZ/H6/A/M is designed with various protections and features. These include an adjustable output voltage, over voltage lockout, over current protection, over-temperature protection, and reverse polarity protection. This makes the device suitable for a wide range of applications. The device also has low ripple and high efficiency, making it suitable for applications requiring high frequency operation.

The REC 3-4809SRWZ/H6/A/M is designed to be easy to use and install. The device has an integral heatsink that helps with cooling and the device has a small footprint, making it suitable for integration in small form factor enclosures. The device can be installed in an industry standard DIN rail or in a panel mountable enclosure.

In summary, the REC 3-4809SRWZ/H6/A/M is an isolated half-bridge DC-DC converter intended for high-power applications such as motor drive systems, electric vehicles, avionics, battery-charging systems, and LED lighting systems. The device is designed with a series-mode connection, wide input voltage range, low ripple, and high efficiency for reliability and performance. Furthermore, the device features various protections for safety and durability in a range of operating conditions, making it suitable for a wide range of applications. Finally, the device has a small form factor for easy integration in enclosures.
