Linear Power Supplies

Linear power supplies are a type of electrical device designed to convert alternating current (AC) from the wall outlet into a stable direct current (DC) voltage for powering electronic circuits. These power supply units (PSUs) regulate the voltage and offer a clean and low-noise output. Embedded linear power supplies integrate within a larger system, providing power to the internal components. These open-frame power supplies lack an enclosure, which makes them lighter, more compact, and allow better heat dissipation. Additionally, linear power supplies come in either AC linear power supplies or DC linear power supplies.

Unmatched Benefits of Embedded Linear Power Supplies

Embedded linear power supplies, especially in the open frame format, offer several advantages for specific applications, including: 

  • Simplicity and Ease of Integration:  Open-frame linear power supplies have a basic design with a few components that easily integrate into a circuit board.
  • Low Noise: These power supplies provide a clean and quiet output voltage, which is crucial for sensitive electronic components that can be disrupted by electrical noise.
  • Low Cost: Due to the simple design, embedded linear power supplies are generally less expensive than their switching counterparts. 
  • Compact Size: Open frame designs minimise bulk, allowing a space-saving solution within your embedded system

Linear Power Supplies vs. Switching Power Supplies

Linear and switching power supplies convert AC current to DC by using different approaches. Linear power supplies utilise a transformer to step down the voltage, then regulate it with a component that dissipates excess power as heat. This makes them simple and suitable for low-noise applications. Switching supplies, on the other hand, use transistors to rapidly switch the current on and off, creating a high-frequency signal that's easier to manipulate with transformers. This allows for smaller sizes and higher efficiency but can also introduce electrical noise.

Typical Applications of Linear Power Supplies

Linear power supplies are essential components in many electronic devices and systems due to their ability to provide a stable and noise-free output voltage. Some typical applications where linear power supplies are commonly used include:

  • Audio Equipment
  • Medical Devices
  • Laboratory and Test Equipment
  • Communications Equipment
  • Industrial Control Systems
  • Consumer Electronics
  • Computing and Data Centers
  • Precision Instrumentation
  • Automotive Electronics
  • Renewable Energy Systems
