General Description
The ACT5101-1 high voltage 3
phase brushless DC motor drive
combines a 500 VDC, 40A high
power output stage along with
low power digital input and gate
drive stages. A digital lock-out
feature protects the output stage
from accidental cross-conduction
thus preventing shoot-through
conditions. The ACT5101-1 also
includes a floating gate drive
design for each upper and lower
transistor. On-board gate drive
supplies provide a continuous
floating voltage for each upper
and lower transistor, even during a
motor stall.
The high power output stage
rated at 500 VDC, 40A is capable
of delivering over 20 kW to the
load even after derating. This is
accomplished through the use of
high power IGBTS with ultra-fast
recovery rectifiers in parallel.
The ACT5101-1 utilizes power
hybrid technology to provide the
highest levels of reliability and
lightest weight while requiring the
smallest amount of board space.
The ACT5101-1 is available with
military processing and operates
over the full -55 to +125 degrees C
temperature range.
This makes the ACT5101-1 ideal for
all military, space,and commercial
avionics' applications. These incl-
ude electro-hydrostatic actuators
[EHA's] and electro-mechanical
actuators [EMA's] for flight surface
control, missile fin actuators, thrust
vector control, electric brakes,
fuel
and
cooling
pumps.
