Mitsubishi IPM L1/S1-Series Application Note
Power supply terminals for control IC and driving
IGBT. Supply power commonly to lower arms and
individual, insulated power to upper arms.
For 6in1 and 7in1 types, 4 independent power
supplies are required; three to upper arms and one
to lower arm.
UV lock-out functions if power is 12.5VDC or
lower. Control signals are not effective for
operation under this condition. Fo signal is output.
Ground for reference power supply for lower arms.
This ground is common to each of three phase for
6- or 7-element types. This is also the ground of
control power supply. Bus line current should not
be allowed to flow through this terminal to avoid
noise influences.
PCB pattern should not be such that connects this
terminal and N.
This terminal is internally connected to inverter
ground N. Difference in electric potential between
N and VNC may occur in practical operation.
Grounds for reference power supply for upper arm
of each phase.
Lower power supply impedance as much as
possible for greater resistance to noise.
Insulate each phase of U, V and W.
Input terminals for controlling IPM switching
operation. Operates by voltage input signals.
Internally connected to comparator.
In usual applications, external pull-up resistor is
connected to control power supply, and external
opto-coupler for insulation
connected.
As these terminals are susceptive of noise, design
a shortest route in pattern layout and also take
care for wiring. Connect a capacitor having good
frequency characteristics between power supply
and GND.
This terminal is used with R
The purpose of this terminal is to prevent increase
in P-N voltage, which is caused by regenerative
current produced when AC motor decelerates.
In usual applications, external pull-up resistor is
connected to control power supply, and external
opto-coupler for insulation
connected.
This terminal has the same structure as control
signal terminals, accordingly are susceptive of
noise. Take similar measures.
If power is 16.5VDC or higher, operation is not
guaranteed under short circuit condition. This is
due to IGBT gate characteristics.
Typical value is 15VDC. In order to prevent
malfunction caused by noise and ripples in supply
voltage,
favorable frequency characteristics very close to
IC terminals.
