High-Frequency Transformer Application Case in Medical Equipment

High-frequency transformers serve as critical components in medical equipment, where stability, precision and safety are paramount. A typical application lies in portable ultrasound scanners, widely used in clinical diagnosis and emergency care. These devices adopt 100kHz-500kHz high-frequency transformers to convert 220V AC power to low-voltage DC (12V/24V), powering the scanner’s signal processing unit and transducer.

The transformer features an isolated design to prevent electric leakage, complying with medical electrical safety standards (IEC 60601). Its compact structure reduces the scanner’s overall weight by 25%, enabling easy portability for bedside examinations. With a conversion efficiency of up to 98%, it minimizes heat generation, avoiding interference with the scanner’s temperature-sensitive components and ensuring stable image quality.

Another case is in medical X-ray machines. High-frequency transformers (20kHz-100kHz) boost low voltage to the high voltage (up to 150kV) required for X-ray emission, with ultra-low voltage ripple (≤0.5%). This ensures uniform X-ray intensity, enhancing diagnostic accuracy. These applications highlight the transformer’s role in safeguarding medical equipment performance and patient safety.
