HVAC (Air conditioning)

Heating, Ventilation and Air Conditioning (HVAC) systems have become increasingly commonplace. However there has been a clear drive towards greater efficiency to meet the demand for more sustainable and eco-friendly units. Improving overall system efficiency and thermal performance is fundamental to this change through variable speed compressors or inverter technology. In addition, smart HVAC systems are increasingly interconnected and draw data from both internal and external sensors including external temperature, humidity, brightness, and even the position of the sun.

  • 開(kāi)始采用PWM驅(qū)動(dòng)無(wú)刷直流電機(jī)控制
  • 電機(jī)驅(qū)動(dòng)MOSFET必須以低RDSon和良好的熱阻抗來(lái)滿足峰值高電流需求
  • 如果過(guò)載情況會(huì)降低電池和柵極電壓，則可能需要具有強(qiáng)線性模式性能的MOSFET來(lái)提供反向電池保護(hù)
  • MOSFET可能需要滿足UL2595等的具體間距要求
  • 為小尺寸優(yōu)化的電荷平衡MOSFET，通常裝在可移動(dòng)電池組中——每個(gè)電池一個(gè)
