types because they are required to
supply the high current gate drive
pulses to the IPM’s internal gate
driving circuits. The DC to DC
converters are powered from a single
24VDC supply connected at CN3.
The 24VDC supply is decoupled by
the electrolytic capacitor C11 to
maintain a stable well filtered source
for the DC to DC converters. The
current draw on the 24V supply will
range from about 75mA to 200mA
depending on the module being
driven and switching frequency. For
a more accurate estimate it is
necessary to use the IPM’s circuit
current (I D ) versus f C characteristic to
obtain the current required by the
IPM being used. The IPM current
draw can then be adjusted using the
DC to DC converter efficiency
specification to arrive at the current
draw on the 24V supply. Refer to the
general IPM application notes for
detailed information. A power
indicator consisting of an LED (D5) in
series with current limiting resistor
(R16) is provided to show that the
24VDC supply is present.
Controller Interface:
A typical controller interface for
the BP7A is shown in figure 4. The
control inputs (W N ,V N ,U N ,W P ,V P ,U P ,
Br) consist of the opto coupler’s LED
in series with a 180 ? current limiting
resistor. This combination is
designed to provide approximately
16mA of drive current for the
optocoupler when a 5V control signal
is applied. The anodes of the opto
LEDs are tied directly to the 5V logic
power supply (+V L ). An on signal
(IPM control input low) is generated
by pulling the respective control input
low (GND) using a CMOS buffer
capable of sinking at least 16mA
(74HC04 or similar). In the off state
the buffer should actively pull the
control input high to maintain good
noise immunity. Open collector drive
that allows the control input to float
will degrade common mode noise
immunity and is therefore not
recommended. If a different logic
power supply (+V L ) voltage is desired
