Ⅰ. Power Stability Challenges in Healthcare Industry

1. Critical Equipment Reliability Demands

• Life-support systems (ventilators, defibrillators) require voltage stability ≤±1% to prevent operational failures.
• Medical imaging devices (MRI, CT scanners) are vulnerable to voltage fluctuations, causing diagnostic errors.
• Pharmacy cold storage demands consistent voltage to maintain drug efficacy, with temperature deviation <±0.5℃.

2. EMC and Safety Compliance Risks

• Mechanical contacts in traditional stabilizers generate electromagnetic interference (EMI), disrupting adjacent medical equipment.
• Non-certified stabilizers risk violating healthcare safety standards (e.g., UL 60601-1), leading to regulatory penalties.
• Operating room (OR) environments require spark-free designs to avoid anesthesia ignition hazards.

3. 24/7 Continuous Operation Needs

• Emergency departments (EDs) and intensive care units (ICUs) cannot tolerate even momentary power interruptions.
• Mobile medical devices in remote areas face unstable grid issues, risking equipment damage.
