I. Pain Points of Traditional Medical Power Supplies

In emergency equipment such as defibrillators, ventilators, and portable monitors, the power supply system faces three major challenges:

• Bulky: Silicon-based power supplies have low conversion efficiency and require larger heat dissipation modules, resulting in bulky equipment.

• High energy loss: Traditional solutions waste a large amount of electricity during high-voltage conversion, affecting battery life.

• Severe fever: High temperatures may affect the stability of the equipment and even endanger the safety of patients.

These problems are particularly prominent in scenarios such as field first aid and disaster rescue.

II. GaN Technology: The "Game-Changer" of Medical Power Supplies

Gallium nitride (GaN), as a third-generation semiconductor material, is revolutionizing medical power supply design with its high electron mobility, high voltage resistance, and low conduction loss.

(1) Smaller volume, higher power densityThe switching frequency of GaN devices far exceeds that of silicon-based devices, which can reduce the volume of transformers and capacitors, and shrink the power module by more than 50%.

Case: After the portable defibrillator adopted GaN, its weight was reduced by 30%, making it more suitable for emergency personnel to carry around.

 (2) Ultra-high efficiency, extended battery life

The conduction loss of GaN is extremely low, and its power conversion efficiency can reach over 95% (while traditional silicon-based materials only have 80%-85%).

Meaning: Extend the battery life of devices such as ventilators and ECmos, and gain several more hours of life-saving time in case of power failure.

(3) Low-temperature operation, safe and reliable

The low heat generation feature reduces the demand for heat dissipation and avoids the interference of high temperatures on precision medical circuits.

VI. These scenarios are being changed

1. Mobile emergency unit - Single power supply simultaneously supports:

• defibrillation monitor

• portable ventilator

• electric hospital bed
  

• electric wheelchair
  

• scanner
  

• brain stimulator
  

• X-ray
  

• medical devices with lithium batteries, etc

      ...

2. Emergency rescue

Portable medical devices (such as defibrillators, portable ultrasound machines, infusion pumps, monitors, etc.) need to be quickly recharged, especially in emergency situations, ambulance transfers or field rescue operations.

Mobile healthcare and remote diagnosis and treatment: portable testing devices (such as electrocardiographs, blood glucose meters, and handheld PCR devices) used by primary care or family doctors need to have a long battery life.

Emergency power supply system, providing backup power for life support equipment (such as ventilators, ECMO) at disaster sites or during power outages.

3. High-value equipment Management - Intelligent temperature control system ensures:

Surface temperature ≤39℃ (in compliance with GB9706.1 requirements)

100,000 hours without failure

V. Future Outlook: How Will GaN Reshape the Medical Power Supply Ecosystem?

Wireless: The high-frequency characteristics of GaN enable wireless charging blankets to provide continuous power supply during patient transportation.

Intelligentization: Combining AI to predict power demand and dynamically optimize power management.

Global standards: Institutions such as the FDA are accelerating the certification of GaN medical power supplies, promoting their popularization in the industry.

GaN technology is not only an upgrade of power supply, but also an "invisible guardian" for emergency medical care. With the reduction of costs and the maturation of the industrial chain, in the next 3 to 5 years, we may witness "GaN Inside" becoming a standard feature of high-end medical devices.

Emergency rescue is racing against time and power supply is as stable as a rock - GaN is making this vision a reality.
