SINAMICS G150
Engineering Information
Note:
By contrast with the S120 Line Modules and S120 Motor Modules of the SINAMICS S120 modular system (Chassis
and Cabinet Modules) with which a parallel connection can be created using up to four identical individual modules,
the G150 parallel converter is a ready-to-connect converter cabinet unit which is constructed of two lower-output
SINAMICS G150 converter cabinet units or of two Basic Line Modules and two or three Motor Modules. The parallel
converter is ordered as a unit under a single order number. The technical data stated in the catalogs and the tables in
this engineering manual therefore generally refer to the complete G150 parallel converter and already include the
current and power derating factors required for parallel connections. Owing to the length dimensions of the parallel
converters, the G150 is delivered in transport units.
The following table shows the power spectrum of SINAMICS G150 parallel converters. The last column of the table
states (for information only) the individual components from which the relevant parallel converters are built.

Power spectrum of SINAMICS G150 parallel converters
Since all SINAMICS G150 parallel converters always consist of two identical rectifiers on the line side, the rectifiers
can operate as either a 6-pulse or a 12-pulse bridge circuit. The harmonic effects on the supply system are
significantly lower in 12-pulse operation than in 6-pulse operation (see section "Harmonic effects on supply system" in
chapter "Fundamental Principles and System Description").
Different decoupling measures need to be considered on the line side depending on whether the parallel connection
is a 6-pulse or 12-pulse circuit.
Different decoupling measures also need to be considered on the motor side depending on the type of winding
system of the motor (electrically isolated winding systems or one common winding system) and the number of
inverters in the G150 parallel connection (two or three).
For this reason, the boundary conditions to be considered at the line side and the motor side are discussed in more
detail below.
