Power Modules
Power Modules are available in a wide variety of amperage ratings relating to
the required motor current. Power Modules that are rated up to and including
350 A are fixed-mounted in the drive and ship already installed. Power
Modules that are rated above 350 A are shipped separately, therefore site
installation and cable connection is needed. In this case, a lifting cart is
supplied for power cell replacement.
An optional built-in Power Module bypass feature is also available for all drive
ratings. With the Power Module inside pass circuit, the drive can continue to
run without shutting down when encountering a Power Module failure. This
helps ensure a higher level of process reliability. Since the drive uses a solid-
state bypass, the dimensions of the drive do not increase when adding the
automatic bypass option.
Basic Principle of Power Module
The Power Module combines a three-phase rectifier and an “H” bridge
inverter, which is powered from the secondary side windings of the Isolation
Transformer. After rectifying and filtering, it outputs AC current with variable
frequency and variable voltage under the control of four IGBTs using a PWM
switching pattern. Several Power Modules, after being connected in series and
superposed, can output three-phase AC current with adjustable frequency and
voltage to control an AC motor.
