The HCW traction inverters are based on the fully digitalised HCX three-phase drive system for synchronous and asynchronous motors with sinusoidal current conduction and field-oriented control. Tried and tested power electronic components as well as the HCX200 control electronics specially designed for traction technology form the basis for a system of the highest reliability and functionality.
