Contents of this chapter

This chapter contains a description of the diode supply unit. The information is valid for the
ACS880-307LC…+A018 diode supply units.

Operation principle

The core of the diode supply unit is a diode-thyristor bridge. It rectifies three-phase AC
current to direct current for the intermediate DC link of the drive. The intermediate DC link
supplies the inverters that run the motors. There can be one inverter unit only (single drives)
or several inverter units (multidrives) connected to the intermediate circuit. The DSU modules
have inbuilt AC chokes. The AC chokes smoothen the current waveform in the power supply
network and voltage in the DC link of the drive.

The main difference between the ordinary diode-diode bridge and the controlled
diode-thyristor bridge is the controllability. You cannot control the operation of the diodes
but you can control the thyristors. By controlling the thyristors, you can limit the AC current
of the drive at the power up without additional charging circuit in the supply unit or in inverter
units.

There are two control modes for the upper leg thyristor firing: the charging mode and the
normal mode:

•

The charging mode is in operation a short period after the power switch on: the supply
control program controls the thyristor firing angle gradually towards zero while the
intermediate circuit capacitors located in the inverter module(s) get charged.

•

In the normal mode, the thyristor firing angle is 0 degrees: The thyristors operate as
diodes.
