MIL-COTS VIPAC Powers a Helicopter-Borne Laser Diode Countermeasure System
A laser diode is a semiconductor similar to that found in a light-emitting diode. They are numerically the most common type of laser, suitable for a wide range of applications, including incorporating them into tactical vehicles and aircraft for self–protection and missile defense. Compact, high–efficiency lasers are critical for airborne electro-optic countermeasures, and laser diodes provide the requisite compact size, ruggedness, and efficiency.
Our customer provides solutions for government agencies and defense including involving active and passive signal processing systems. One, a laser diode countermeasure system for Army helicopters, is designed in two parts, the command and control board and the laser diode driver board. MIL-COTS VIPACs are used for both parts. The command and control card, one per system, has a VIPAC with three modules, a 15 V, 5 V, and a 24 V brick, trimmable to 15 V, 7 V, and 5 V. The laser driver card, two in each system for redundancy, has a VIPAC with one 24 V brick and a VIPAC with one 15 V brick.
The MIL-COTS VIPAC family of power systems is a class of user-defined, modular power solutions for the most demanding military applications. They incorporate preassembled and tested front ends to provide input transient protection perMIL-STD-704E/F (M-FIAM5B), MIL-STD-704A/E/F, and MIL-STD-1275A/B/D (M-FIAM9). They also compliant to MIL-STD-810F for vibration and shock. Incidentally, the wide trim range of Vicor modules can provide operating voltages as low as 500 mV.
