Non-Isolated AC/DC Linear power supply

For many applications a simple cost-effective AC/DC converter remains the most efficient option. That is where the non-isolated AC/DC linear power supply continues to play an important role. And with Nexperia's portfolio, designers can still produce an efficient converter solution while minimizing costs.

設(shè)計(jì)考慮因素

  • 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)

MOSFET and GaN FET Handbook

Drawing on over 20 years’ of experience, the MOSFET and GaN FET Application Handbook: A Power Design Engineer’s Guide brings together a comprehensive set of learning and reference materials relating to the use of MOSFETs and GaN FETs in real world systems.
