Drives cut harmonics by 97% without needing chokes

03 April, 2023

Siemens has announced a high-performance frequency converter equipped with a “clean power technology” that cuts harmonics by up to 97% without needing line harmonic chokes or DC link chokes. The Sinamics G220 converter is also the first Sinamics drive to be part of Siemens’ Xcelerator digital transformation platform. It is making its debut at the 2023 Hannover Fair.

The drives, which are part of Siemens’ TIA portal, are claimed to be efficient in terms of space utilisation and operation, and simple to engineer. An integrated Web server is claimed to reduce commissioning times “significantly”.

The converters have digital twins in Siemens’ Startdrive drive commissioning tool. This allows the behaviour of a drive to be tested and optimised without needing the hardware.

The drives are also fitted with an IIoT module that allows them to be integrated into cloud and edge applications, increasing the transparency of their applications and, in turn, reducing downtime.

The G220 is equipped with Security Integrated as standard, providing secure communications, integrity and authenticity checks to protect against tampering with the firmware, as well as user management and access control functions.

The new Sinamics G220 frequency converters are the first Sinamics drives to be part of the Siemens Xcelerator portfolio.

The converters offer a choice of hardware options and software functions, allowing them to be adapted to suit applications. For example, they are available with IP55 protection and there are special coatings for harsh environments.

The converters comply with SIL 3 safety requirements.
