Product Description
FSDrive-MX1S Series Matrix Converter
The FSDrive-MX1S series Matrix converter is a new series PWM type medium voltage inverter unit. This unit
offers the following four features:
The power supply regeneration function allows dynamic acceleration/deceleration operations.
•
Enables a clean power supply minus excessive harmonics.
•
This Matrix converter unit causes little voltage distortion and uses little current.
Achieves high efficiency and high power factor.
•
Matrix converter efficiency: approx. 98%, power factor: 0.95 or more (at rated rotation and 100% load)
Achieves output voltage and current of approximate sinusoidal wave.
•
Since the Matrix converter unit has little surge voltage that affects motor, existing motors or cables can be
used without modification.
Torque ripple is minimized.
Configuration
Fig. 1.3 shows typical configurations of FSDrive-MX1S series Matrix converters.
As shown in Fig. 1.3, the FSDrive-MX1S series Matrix converter is composed of three panels:
Transformer Panel
•
Power Cell Panel
•
Control Panel (Some models have one panel commonly used as Control and Transformer Panel because of
•
their capacities.)
Transformer Panel
The Transformer Panel houses a dry-type transformer, 3 kV (3.3 kV)/630 V or 6 kV (6.6 kV)/630 V with
multi-windings. The secondary winding of the multiple transformer is composed of three steps (9 windings)
for 3 kV class or 6 steps (18 windings) for 6 kV class, each of which is connected to a 3-phase input of the
Power Cell.
Several cooling fans are mounted on the Transformer Panel, in which pressurized ventilation fans are stored.
Cooled air brought through the filters on the Transformer Panel and Power Cell Panel front faces passes the
transformer section and Power Cell fin section, flows into the air duct in the panel rear, and is exhausted
through the fan section panel after cooling the main circuit components.
