Improving efficiency in switched mode power supply

Power supply design has traditionally placed a high priority on energy efficiency. The system and the end user will pay more if the power supply is inefficient and has non-negligible power losses. Let’s not forget that the move from linear regulators to more efficient switching technology was made possible by the quest for ever-higher efficiency … Read more

Overview of commercial integrated SMPS

This article will outline several highly integrated electronic components that can be used to create SMPS power supplies that function at a high level with the addition of a few passive external parts. A representative selection of these components will be taken into consideration because there are many integrated solutions for SMPS design available on … Read more

DC power supplies – Part 13 – Power Electronics Course

Depending on the output voltage type, there are two different types of power supply. In fact, they can be divided into AC and DC power supplies. Their types vary depending on the system’s overall requirements and the sophistication demanded by the project specifications. Normal converters don’t always provide enough safety, especially in industrial and medical … Read more

Can Voltage Be Negative? Understanding Negative Voltage

In addition to explaining the nature of a negative voltage, this article briefly discusses how negative voltages are generated and why they are useful in circuit design. The concept of negative voltage is sometimes less intuitive than the concept of positive voltage. Perhaps this is because many low-voltage electronic systems do not use negative voltage … Read more

GaN Transistors Improve Switching Efficiencies

Power electronics have evolved rapidly in recent decades primarily due to increasingly fast semiconductor switches, which make it possible to design smaller components for storing electricity, such as capacitors and inductances. Combined with increased efficiency, this allows the realization of smaller power-electronic components such as power supply units and DC-DC converters. Semiconductor switches have been … Read more

Power Supplies: Understanding the Differences Between Linear and Switching

Linear and switch-mode power supplies provide direct current to power control components and electrical devices. Learn about the differences between the two power supplies and which one is best for your control system. Power Supplies in Industry Alternating current (AC) power is created in a generator or alternator and continuously switches polarity as the generator … Read more

Multiphase Synchronization Technique Reduces Conducted Noise

Military switching DC/DC converters must adhere to strict regulations on the amount of conducted input noise emissions, and they frequently need input filter networks to do so. However, noise can mix in unpredictable ways when DC/DC converter inputs are paralleled, making filter design challenging. This article analyzes the problem and explains how to use the … Read more

Successful hardware projects start with…

Who hasn’t worked on a project that went nowhere or got canceled? Sometimes the project deserves it because it was ill-conceived or poorly executed. Sometimes markets moved or there wasn’t really a need, and sometimes the project was just in chaos from the start. This last reason to get canceled is the one that is … Read more
