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.
