Traction Inverters General
Traction Inverters HTW

The HTW traction inverters are based on the fully digital three-phase inverter system RD52 for synchronous and asynchronous motors with sinusoidal current and field oriented control. Proven power electronics components as well as our control SCE2000, which is specifically designed to meet the requirements of traction applications, form the base of a system with highest reliability and functionality.
