Small, Fast, Stable. That's High Freq.

High-frequency power supplies use switching transistors operating at high frequencies — typically tens to hundreds of kilohertz. The core is a switching converter circuit paired with a small high-frequency transformer, only one-third the size of an equivalent low-frequency supply, or even smaller. This fundamental design shift brings dramatic advantages in size, weight, and performance.

            
 

Compact Size: One-Third the Volume

The most visible benefit is size. Because the transformer operates at much higher frequencies, it can be drastically smaller. A high-frequency power supply occupies only one-third the volume of a comparable low-frequency unit. For applications where space is at a premium — such as telecom cabinets, medical carts, or industrial control panels — this reduction is transformative.

High Efficiency: 85% to Over 95%

Efficiency is another standout advantage. High-frequency power supplies typically achieve efficiencies ranging from 85% to over 95%. Less energy is wasted as heat, which means cooler operation, smaller heatsinks, and lower electricity bills. For B2B customers running equipment 24/7, the energy savings alone can justify the investment.

Fast Dynamic Response and Tight Regulation

High-frequency switching allows for very fast dynamic response. When the load changes suddenly, the power supply adjusts almost instantly. Voltage regulation is tight — output stays stable even under fluctuating input or varying load conditions. This precision is critical for sensitive electronics like medical instruments and industrial controllers.

Typical Applications

Modern electronic devices almost exclusively use high-frequency power supplies. Typical products include high-frequency switching plating power supplies, inverter welders, HLG2 dust removal power supplies, and telecom rectifier modules. From communication base stations to hospital equipment, high-frequency power is the standard.

The Trade-Off: Complexity and Component Quality

The disadvantage is a more complex circuit, requiring higher quality components and careful EMC design. But at KRECO, we embrace this complexity. We select premium switching transistors, high-grade capacitors, and meticulously design the layout to minimize electromagnetic interference. The result is a power supply that is not only small and efficient but also reliable and compliant with global EMC standards.

The Mainstream Choice for B2B Customers

For B2B customers prioritizing compactness, lightweight, and energy saving, high-efficiency power supplies are the mainstream choice today. Whether you are designing next-generation telecom equipment or upgrading industrial machinery, KRECO's high-frequency solutions deliver the performance you need in a package that fits your space constraints.
