鉄道輸送 - インバータおよび電源

軌道輸送および信号 - インバータ

設計上の考慮事項

Typical railway power conversion systems include AC/DC rectifiers, DC/AC inverters, and DC/DC converters. The two key performance measures are power capabilities and efficiency. Typical motor control functions include driving IGBT/relevant power stages, sensing the motor speed/position accurately and diagnosing and driving the system safely to avoid any malfunctions of the inverter.

  • Auxiliary power solutions that provide high efficiency at light load (~10%) and offer very low stand-by power consumption
  • High efficiency solutions through soft-switching techniques such as LLC resonant DC/DC, phase-shifted full-bridge DC/DC and ZVS PWM DC/DC, using both analog and digital implementation
  • High power density by using GaN power blocks, Dualcool(TM) MOSFETS and FET power blocks with low gate charge and low RDS(ON)
  • Solutions that meet EMC, EMI and electrical safety requirements
