FAQS 4

What is the power supply for an auxiliary inverter?

Local power supply (3 AC 400 V 45 kVA/ 63 A) For service and maintenance purposes, the auxiliary inverter can be supplied with a 3 AC 400 V local network supply via the train busbar. The APS picks up the voltage and feeds the 110 V DC grid and charges the vehicle’s batteries. Output converter Low-voltage unit

How does an auxiliary inverter work?

For service and maintenance purposes, the auxiliary inverter can be supplied with a 3 AC 400 V local network supply via the train busbar. The APS picks up the voltage and feeds the 110 V DC grid and charges the vehicle’s batteries. Output converter Low-voltage unit The Low Voltage Unit (LVU) consists of a 3 AC inverter and a battery charger.

What is a traction inverter auxiliary power supply?

Designed to meet the demanding voltage and reliability requirements of electric, hybrid, and plug-in hybrid electric vehicles (EVs, HEVs, and PHEVs), this turn-key auxiliary power supply solution for traction inverter systems delivers a compact, efficient, and robust solution for high-power traction inverter applications.

Why do solar inverters need auxiliary power supply?

The control domain, consisting of microcontrollers, gathers information from all of the above to enable efficient and reliable power conversion. With such dependency on so many different devices, it only makes sense that the auxiliary power supply is just as important to proper solar inverter operation.
