Washing machine / Dishwasher

Sustainability and energy efficiency have become a key factor in all home appliances, and particularly those perceived to be heavy users of electricity such as washing machines and dishwashers. In part this is driving more intelligence into systems, to better sense and control water and detergent usage, but also to connect with the outside world for remote (smartphone app) control. In addition, factors such as low acoustic noise are increasingly having an impact. This is leading to greater use of BLDC motors, which can also improve life-expectancy and reduce maintenance.

設(shè)計(jì)考慮因素

  • 開始采用PWM驅(qū)動(dòng)無刷直流電機(jī)控制
  • 電機(jī)驅(qū)動(dòng)MOSFET必須以低RDSon和良好的熱阻抗來滿足峰值高電流需求
  • 如果過載情況會(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.
