This is the output indicating faulty state of IPM.
Faulty modes are classified into overheat, load
(arm) short circuit, control power supply under
voltage protection. This output does not make
distinction of these modes, however. The terminal
is an open collector with resistor connected in
series.
opto-coupler (or LED) between this terminal and
V
Power supply terminal to inverter.
In usual applications, connect this terminal to
positive (+) line after rectifying AC line.
Internally connected to collector of upper arm
IGBT. In order to suppress surge voltage caused
by inductance component of PCB pattern, connect
a smoothing capacitor very close to P and N
terminals. It is also effective to add a film capacitor
of good frequency characteristics.
Power supply ground of inverter.
In usual applications, connect this terminal to
ground (-) line after rectifying AC line.
Make connection so that bus line current flows
through this terminal. Internally connected to
emitter of lower arm IGBT. This terminal is also
connected to reference control ground V
Difference in electric potential between VNC and N
may occur in practical operation due to IPM’s
internal parasitic inductance.
Inverter output terminal.
A load such as AC motor is connected in usual
applications. Take care for generation of surge
voltage. Internally connected to mid point of IGBT
modules (IPM) of half-bridge configuration.
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, power dissipating resistor
(brake resistor) is connected between this terminal
and upper arm.
Since this terminal is designed taking into account
regenerative current produced when AC motor is
decelerates, the current rating of this terminal is
about 50% of that of IGBT chip used for U, V, and
W.
This terminal cannot endure use involving special
control that allows a large current to flow.
