Designing power supply units

At Hegawei, we understand the importance of delivering high-quality power design solutions that meet our customers’ needs. That’s why we have a systematic and thorough approach to power design, which includes the following steps:

  1. Defining specifications to ensure we understand the project requirements.
  2. Determining the best topology to meet those requirements.
  3. Designing efficient inductive components.
  4. Creating detailed schematics and selecting components to ensure optimal performance.
  5. Carefully bringing the board to life and performing thorough functional tests.

We also create evaluation boards to verify that our power supplies meet all performance requirements.

We take pride in our commitment to delivering power design solutions that not only meet, but exceed our customers’ expectations. Contact us today to learn how we can help bring your project to life.

PCB board designing

The proper layout of a switching mode power supply PCB is critical for successful design, especially with advanced components such as GaN, GaN HEMTs, and SiC transistors. We has extensive experience in designing PCBs for these components, which directly impacts efficiency, component temperature, electromagnetic radiation and conducted emissions.

We offers consultation for designing efficient layouts for switching power supplies to ensure optimal performance. Additionally, we utilize the KiCAD EDA software to design the PCB layouts in-house.


Tests vary depending on the type and specifications of the power supply, and the purpose of the testing.

By testing a switch mode power supply, we can determine:

  1. If the power supply meets its specifications, such as input voltage range, output voltage and current, ripple and noise, line and load regulation, efficiency, and protection levels.
  2. If the power supply is reliable and meets the desired MTBF requirement.
  3. If the power supply is stable and can maintain its performance under different environmental conditions and changes in load.
  4. If the power supply is safe to use, with proper protection mechanisms against overload, short circuit, and over-temperature.

In summary, testing a switch mode power supply provides information on its performance, reliability, stability, and safety.
