DC-DC converters are electrical circuits that convert direct current (DC) from one volt level to another. RE-0509S is a high performance DC-DC converter, which has a wide application field and working principle.

Application Field

RE-0509S is mainly used in aerospace, defense, transport, telecom and industrial automatic control fields, as well as some new energy power supplies, such as wind, solar and so on. It is also applicable for power transmitter systems, electric power steering systems, on-board battery systems and so on.

As a high power DC-DC converter, RE-0509S can provide very fast dynamic response capability, which makes it a good choice for the applications that require very fast transition response characteristics, such as support for mobile phones, laptop computers, tablet PCs and other handheld digital devices.

Working Principle

RE-0509S adopts the semi-bridge inverter topology, and it has a wide tension range. Its working principle can be divided into three parts, namely the current detection circuit, the pulse width modulation control circuit (PWM) and the power switch module.

The current detection circuit is to detect the current of the power switch module. Through the feedback signal, the pulse width modulation controlled circuit (PWM) will control the switch time of the module, thereby controlling the current output of the module in the set range. Finally, the power switch module is the switch tube device that is connected in the circuit according to a certain interval, so that the current of the whole circuit can be controlled by controlling the device switch.

In addition, the RE-0509S also adopts a number of advanced technologies, such as soft start circuit, fast fault protection circuit and current limitation soft start circuit, to ensure the power switch module can work safely and reliably.

In order to make the power supply output voltage more accurate, the RE-0509S is equipped with a high-precision voltage linear regulator circuit, which can ensure the output voltage accuracy is better than 0.2%.

Conclusion

In summary, RE-0509S is a high performance DC-DC converter with wide application field and working principle. It adopts the semi-bridge inverter topology and has a wide tension range. Through the current detection circuit and the pulse width modulation control circuit (PWM), it can control the current output of the module in the set range. It is also equipped with a number of advanced technologies, such as soft start circuit, fast fault protection circuit and current limitation soft start circuit, to ensure the power switch module can work safely and reliably.
