Circuit Explanation: The BG2B is a basic two channel gate driver designed around the recommended
application circuits for the Powerex M57159L-01, VLA503-01 and VLA504-01 hybrid IGBT gate drivers in
combination with either VLA106-15242 or VLA106-24242 isolated DC to DC converters.
A functional block diagram of the VLA503/504-01 and M57159L-01 hybrid gate drivers is shown for
reference in Figure 1. These gate drivers are optimized for use with Powerex NF and A series IGBT modules.
The drivers use a high speed open collector type opto-coupler to provide 2500VRMS isolation of control signals.
The output stage is designed to provide high current gate drive with the appropriate on- and off-state bias
voltages for large IGBT modules. The gate driver includes a desaturation detection circuit to provide protection
against short circuit conditions. For additional detailed information on the characteristics and operation of these
gate drivers please refer to the individual device data sheets.
Figure 2 shows a block diagram of the VLA106-15242 and VLA106-24242 hybrid DC to DC converters.
These two devices are identical except that VLA106-15242 is designed to operate from a 15 VDC input and the
VLA106-24242 is designed to operate from a 24 VDC input. These DC to DC converters use a transformer to
provide 2500VRMS isolation for gate drive power. The converter’s regulated 24VDC output is split using a
resistor and zener diode to provide +15.8V and -8.2V for the hybrid gate driver.
For additional detailed
information on the operation of the hybrid gate drivers and DC to DC converters please see the individual device
data sheets.
A complete schematic and component selection guide for the BG2B is shown in Figure 3. The board will
normally be operated with two input voltage sources. A 5V logic source (+V L ) provides drive for the high speed
opto-couplers inside the hybrid gate drivers and pull-up voltage for the fault signal isolation optos OP1 and OP2.
A control power supply (+V S ) provides power for the gate driver and is connected to the primary side of the DC
to DC converters at pins 8,9 and 10,11. The +V S source is decoupled with the low impedance electrolytic
capacitors C4 and C8. These capacitors are connected close to the input pins of each DC to DC converter to
provide a stable, well-filtered DC source. A 150uF capacitor was selected for C4 and C8 to provide the required
ripple current and filtering assuming a maximum driving load and a significant distance to the main filter
capacitor of the +V S supply. These capacitors will be larger than necessary if the driving load is smaller or the
V S supply main filter capacitors are nearby. The DC to DC converters provide isolated gate drive power which
consists of +15.8V (V CC ) at pin 3 and -8.2 (V EE ) at pin 1 with respect to common at pin 2. The gate drive power
supplies are decoupled using the low impedance electrolytic capacitors C1, C2, C5, and C6. It is very important
that these capacitors have low enough impedance and sufficient ripple current capability to provide the required
high current gate drive pulses. The 82uF low impedance capacitors used on the BG2B are sized to supply 5A
gate pulses at a 10KHz rate. If the application is operating at lower frequency or lower peak current it may be
possible to reduce the size of these capacitors.
The isolated V EE and V CC supplies provided by the DC to DC converters are connected to the hybrid
gate drivers at pins 4 and 6 to provide gate drive power. The hybrid gate driver amplifies the control input signal
and produces high current gate drive at pin 5. The gate drive current is adjusted by selecting the appropriate
series gate resistance (R G ). R G will normally be adjusted to provide suitable drive for the module being used
considering dynamic performance, losses and switching noise.
For more information on selecting R G see
Powerex IGBT module application notes. Protection against gate voltage surges is provided by DZ1, DZ2, DZ4,
and DZ5. These zener diodes also help to control short circuit currents by shunting miller current away from the
gate.
