DC-DC converters represent a type of power electronics systems used to transform different power levels from one DC voltage to another in a variety of applications. While the concept of DC-DC conversion is simple, the implementation and associated technologies for power conversion are quite complex. In this article, we will provide an overview of the application field and working principle of the PEM2-S5-S12-D DC-DC converter.

Application Field

The PEM2-S5-S12-D DC-DC converter is a state-of-the-art product designed to step-down from high to low voltage in a wide range of industrial, medical and other applications. It is capable of handling up to 75 W and allows for efficiency up to 93%. As such, it is ideal for applications in robotics, power supplies, audio equipment, LED lighting and a wide array of other commercial, military and medical uses.

The PEM2-S5-S12-D DC-DC converter provides a wide range of input voltage levels, making it suitable for input DC sources of 24V up to 300V and with a wide tolerant input voltage ranging from 25V to 400V, making it even more flexible for a variety of input DC sources.

In addition, the PEM2-S5-S12-D comes in a range of different voltage outputs between 1.2V and 7.5V, allowing for the application to be well-matched to the needed power requirements.

Working Principle

The working principle of the PEM2-S5-S12-D DC-DC converter is based on electrical switch-mode power conversion. This power conversion method involves the use of power MOSFETs (metal-oxide-semiconductor field-effect transistors) to switch the regulated power on and off at a frequency that can range from 50kHz up to 1MHz. By using multiple MOSFETS, the load is driven at a lower frequency, thereby reducing switching losses.

The power conversion also involves the utilisation of magnetic components, such as inductors and transformers, that are variable and adjustable by external control. Inductors are used to store energy over a short period of time and consequently to transfer the energy to the secondary side of the converter. The transformers provide galvanic isolation between the primary and secondary sides of the power conversion circuit, thereby preventing the high voltage input signal from affecting the more sensitive end-user devices and applications.

The output voltage waveform is regulated through the use of a totem-pole style controller that is programmed with the desired set parameters, such as input voltage, output voltage or current limit, output voltage level, and other settings that are needed. In addition, the controller also manages the switching and sensing operations in order to deliver the desired output voltage and current levels. As a result, the PEM2-S5-S12-D DC-DC converter is able to deliver its high-efficiency output with a low ripple noise factor.

The PEM2-S5-S12-D DC-DC converter is a versatile power conversion circuit that is suited for a variety of end-user applications. Through the use of electrical switch-mode power conversion and magnetic components, it is capable of providing efficient and accurate voltage and current control. In addition, the adjustable parameters allow for the use in a wide range of potential applications, making it an ideal choice for commercial, military and medical power conversion requirements.
