Controller Interface:
A typical controller interface for the BP6A is shown in figure 4. The control inputs (W N ,V N ,U N ,W P ,V P ,U P )
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 the
current limiting resistors (R8-R13) must be adjusted. The value of the limiting resistor can be calculated by
assuming the forward voltage drop of the optocoupler’s photodiode is approximately 1.5V and that the
buffer/driver on-state output voltage is approximately 0.6V. For example, if a 15V logic power supply is desired,
the required limiting resistors would be: (15V-1.5V-0.6V) ÷ 16mA = 800 ? .
If the IPM’s built in protection is activated it will immediately shut down the gate drive to the affected IGBT
and pull the associated FO pin low. This causes the fault isolation opto to turn on and pull the fault feedback
signal (Pin 2 of CN1) low. When a fault is detected by the IPM a fault signal with a minimum duration of 1ms is
produced. Any signal on the fault line that is significantly shorter than 1ms can not be a legitimate fault and
should be ignored by the controller. Therefore, for a robust noise immune design, it is recommended that an RC
filter with a time constant of approximately 10us be added to the fault feedback as shown in figure 4. An active
fault signal indicates that severe conditions have caused the IPM’s self protection to operate. The fault feedback
signal should be used by the system controller to stop the operation of the circuit until the cause of the fault is
identified and corrected. Repetitive fault operations may result in damage to the IPM.
Printed Circuit Layout:
Figure 5 shows the printed circuit layout of the BG6A interface circuit. The compact 80mm x 140mm
circuit board with only 58 components provides a complete isolated six channel driving circuit with short circuit,
over temperature and under voltage protection. This clearly demonstrates the advantage of using L-Series
Intelligent Power Modules. One important feature of this PCB is the use of separate ground plane islands for
each of the isolated driving circuits, logic level interface, and 24V power supply. Six of the islands are tied to the
common pin of the IPM’s six isolated control power supplies (IPM pins 13, 17, 21, 25, 29, 33). The remaining
two islands are connected at the logic ground (pin 1 of CN1) and 24 VDC power supply ground (pin 1 of CN3)
respectively. This layout is designed to prevent undesirable coupling of noise between the control side and the
floating gate drive channels. The BP6A PCB is designed to plug directly onto the control pins of the L-Series
IPM. This configuration helps to maintain good noise immunity by providing minimal interconnection distance.
