DC DC Converters

DC to DC converters, also known as DC-DC converters, are used to convert direct current (DC) power from one voltage level to another. In recent years, DC-DC converters have become increasingly popular as a result of higher efficiency, smaller size, and lower cost than traditional power transformers. These converters, as the name implies, are typically used to convert household voltage levels into an alternate level, such as 12V to 24V, 24V to 48V, etc. They can also be used to convert various alternating current (AC) voltages into DC power.

The diverse range of application fields and the wide range of available configurations of DC-DC converters demonstrate the significance of these devices in today’s efficient electrical power systems. DC-DC converters are used in various sectors of the economy, ranging from consumer electronics to industrial and automotive applications. DC-DC converters have found their way into the hearts of many as a result of their versatility and affordability. This article, focuses on the application fields and working principles of the REC5-4805DRWZ/H4/A DC-DC converter.

Application Field

The REC5-4805DRWZ/H4/A DC-DC converter is a highly reliable, compactly built, cost-effective power supply solution for systems in the harsh environment. It is well suited for industrial applications, including control equipment, communication centers, order pickup systems, etc. It is also well suited for outdoor power supply systems. The converter is designed for universal input, accepting both single phase and three-phase input, and delivers 12V DC or 24V DC at 5A. Its wide operating temperature range of –40C to 85C allows it to be used in various extreme environmental conditions.

The REC5-4805DRWZ/H4/A DC-DC converter also features integrated protection against electrical surges, input over voltage, short circuit, and over-temperature. Its 3000Vdc input-to-output isolation and ultra low input ripple noise of up to 100mV make the device ideal for use in medical, industrial and mil-aero environments.

Working Principle

The REC5-4805DRWZ/H4/A DC-DC converter works on the principle of “Pulse Width Modulation” or PWM. This is a switching technique which uses two or more signals to control a variable power output. In the REC5-4805DRWZ/H4/A DC-DC converter, PWM is used to control the output voltage. Essentially, the output voltage is produced by adjusting the duration and frequency of the pulses. This method allows the output voltage to be accurately controlled over a range of input voltages. The converter also features an integrated control loop which regulates the output voltage and ensures proper operation at all times.

On the input side of the converter, the input voltage is rectified to DC, then passed through an input filter, which attenuates high frequency noise, before being fed to the converter\'s switching stage. The converter\'s switching stage consists of fast switching transistors which act as an electronic switch. This switch is controlled by the integrated control and feedback circuit, which adjusts the switching waveform in order to maintain a constant output voltage under varying input conditions. The output voltage is then passed through an output filter to remove any residual switching noise.

The REC5-4805DRWZ/H4/A DC-DC converter combines an integrated control loop with PWM technology to offer high efficiency and superior voltage regulation in a very compact package. It is a reliable, cost-effective, and highly efficient power supply solution for harsh environment applications. The device\'s wide operating temperature range allows it to operate even in extreme environmental conditions, making it ideal for both indoor and outdoor applications.
