Good EMC Performance

Precision medical equipment requires good EMC performance to prevent data transmission interference and reduce the risk of system failure;

High reliability

Medical equipment systems are expensive and maintenance costs are high. Therefore, the requirement for power modules should be long-term stable operation with high reliability;

Low leakage current, and safety

Most of the medical equipment is in direct contact with the human body. This necessitates the use of a power supply with high isolation voltage and low leakage current to guarantee sufficient safety.

Therefore, medical devices have high requirements for reliability, medical certification compliance, and EMC performance of their internal conversion power supplies.
