DC DC Converters

A DC to DC Converter (called DC/DC Converter) is a device that converts a direct current (DC) from one voltage level to another voltage level. The model QRW025A0Y is a dual output Isolated DC/DC Converter getting inputs in wide range from 9V to 75V, and either 5V or 12V fixed outputs. It is popular for its strong working capacity, huge power, and reliable security.

Application Field

The QRW025A0Y DC/DC converter is suitable for use in a wide variety of applications, including but not limited to:

• Power supply systems
• Lighting control systems
• DC Motor control systems
• Battery powered systems
• Remotely located systems
• Renewable energy systems
• Telecommunication systems
• Automobile and aircraft systems

The model is also highly regarded for its robustness and durability, equipped with overvoltage protection reverse connection protection and thermal protection. It can withstand tough conditions and extreme temperatures making it ideal for installation in harsh environments.

Working Principle

The QRW025A0Y isolated DC/DC converter is based on the resonant zero-current switching (ZCS) and zero-voltage switching (ZVS) conduction principles, which is a flyback type of direct current-to-direct current converter that relies on a high frequency transformer. It uses an isolated transformer to transfer electric energy from the input side to the output side. On the input side, an inductor absorbs the electric energy, and on the output side, an inductor generates the electric energy.

The spatial isolation between input voltage and output voltage is provided by the input and output windings on the transformer, and the physical isolation is provided by the plastic case. The input cable works as one of the electric energy transmission paths and contains at least two of the cables necessary for current transmission. The other cables needed for current transmission depend on the type of application where the converter is used.

The QRW025A0Y isolated DC/DC converter also utilizes a feedback loop which allows for accurate control of the output voltage and current. This is achieved by monitoring and comparing the feedback signal from the output to the reference voltage. If there is any discrepancy, the error signal is then fed back to the converter, and the circuit is adjusted to make the output voltage and current stable and accurate.

The QRW025A0Y is a highly efficient converter with a 95% conversion efficiency in light load and peak efficiency of more than 90%. This helps to reduce power loss and reduce energy consumption, which is beneficial for the environment as well as cost savings.

The QRW025A0Y is a popular DC/DC converter, due to its efficient and reliable operation and the wide range of applications it finds use in. It’s ideal for use in a wide variety of applications ranging from Power Supplies to Lighting Control Systems, and many more.
