Efficiency contributes to sustainability

The efficiency of power supplies is a key value for reducing CO₂ emissions in industrial applications.

What is meant by the efficiency of power supplies?

The value "efficiency" describes how efficiently a power supply converts the mains voltage into the required output voltage. The higher the efficiency, the lower the power losses and thus the less energy is wasted. PULS achieves efficiency values of over 95 % with its switched-mode power supplies. This leads to decreasing CO₂ emissions in operational use. In the following blog article, you can find out why this also pays off financially for companies.

How are efficiency, lifetime and reliability related?

Efficiency, MTBF and lifetime explained

A high efficiency has a positive effect on the reliability and lifetime of the power supplies. Robust and durable devices need to be replaced less frequently, thus protecting the environment. Right from the development stage, PULS ensures that the power supplies will work maintenance-free for many years. You can find out more about the significance of MTBF (Mean Time Between Failures) and lifetime in our white paper.

How to correctly measure the efficiency of a power supply!

Measure efficiency correctly

Precise efficiency measurement is complex and requires expensive equipment. System developers should therefore be able to rely on the values given in the manufacturer's data sheet. However, this is not always the case. In the following blog post, PULS makes transparent how test engineers measure the efficiency of power supplies and what you should look out for if you want to carry out measurements yourself.

Research & development contributes to sustainability

PULS developers are continuously researching to increase the efficiency of our power supplies.

Many small steps lead to more efficiency

To further increase efficiency the PULS developers rely on the use of the wide bandgap material silicon carbide (SiC) and a sophisticated LLC converter topology, for many products. Every detail, in terms of circuit and thermal design, was calculated, simulated and optimized in many variants using elaborate procedures and partly self-written software. In total, these many development steps have a significant effect on the reduction of energy losses.

Cool design in power supplies means a longer service life and thus less electrical waste.

Less electronic waste thanks to "Cool Design"

To ensure that power supplies last for a long time, the temperature in the devices must remain as low as possible. In the development process, PULS pays attention to the "Cool Design" of its power supplies. This involves the interaction of three factors that lead to lower heat generation and thus a long service life: Firstly, the consistently high efficiency, secondly the optimized dissipation of heat generated by the remaining power losses to the environment and thirdly the well thought-out arrangement of temperature-sensitive components in the device.
