Auxiliary Power Supply System

Auxiliary Power Supply System

We supply auxiliary power supply systems that are compact, lightweight, highly efficient and have high redundancy.

Toshiba provides a full auxiliary power supply system lineup that meets various needs, and support a high level of passenger service. We also have a varied supply record in Japan and overseas.

Features

Toshiba's auxiliary power supply systems have high transient response, stable control, compactness, lightweight and low noise. We have a large variety of these systems including a 2-level SIV (Static Inverter) which cover the range between 70 kVA and 260 kVA, high efficiency 3-level SIV, redundancy considered standby dual SIV, and a dual mode SIV which switches over from the inverter for traction motor to APU in the event of an SIV failure.

Benefits & Value

3-level SIV system

  • The inverter loss has been reduced,realizing in an efficiency of 96%*1.
  • Each function is modularized,facilitating replacement work in the event of a breakdown.

Standby dual SIV system

  • Normally, one of the two APUs (SIV1 or SIV2) is activated. In case the active APU fails, the other APU is activated and continues to supply electricity.
  • A 2-in-1 inverter unit is employed, realizing that is compactness and lightweight.
