2. Typical Medical Power Supply Architecture

Medical power supplies are typically composed of an EMI filter, Power Factor Correction (PFC) circuit, LLC high-efficiency converter, isolation transformer, and output filter.

Through an optimized power architecture design, medical power supplies can effectively reduce electromagnetic interference (EMI), improve power conversion efficiency, enhance insulation protection, and deliver stable and reliable DC output. These features help ensure compliance with the safety requirements of the IEC 60601-1 standard for medical equipment applications.

3. MOPP / MOOP Concept (IEC 60601-1)

MOPP (Means of Patient Protection) and MOOP (Means of Operator Protection) are key safety requirements defined in the IEC 60601-1 medical equipment safety standard.

(1) MOPP is designed to protect patients from electric shock hazards and requires more stringent standards for insulation, dielectric strength, leakage current, and safety distances.

(2) MOOP is intended to protect operators and healthcare personnel, with safety requirements that are less stringent than those for MOPP.

Medical power supplies compliant with 2 × MOPP provide a higher level of electrical isolation and protection, making them ideal for use in medical devices, medical displays, diagnostic equipment, and patient monitoring systems.

4. EMI Performance vs Leakage Current

In medical power supply design, Y capacitors and other filtering components are commonly used to reduce EMI (Electromagnetic Interference) and ensure compliance with EMC standards. While Y capacitors effectively improve EMI performance, they can also increase leakage current. Therefore, medical power supplies must achieve an optimal balance between EMI suppression and low leakage current to meet the requirements of IEC 60601-1 medical safety standards and ensure patient protection.

5. Key Isolation Design Elements

By incorporating Triple Insulated Wire, Reinforced Insulation, adequate Creepage Distance, and Clearance Distance design, the power supply complies with IEC 60601-1 and 2×MOPP safety requirements, enhancing patient safety, insulation reliability, and overall system safety.

6. Verification Process

Include: Electrical Performance, Thermal Analysis, EMI/EMC Test, Safety Test, Environmental Reliability, Life Test, etc.

7. Global Regulatory Compliance
