Mid-power Maxi, Mini, and Micro modules for military and aerospace applications

January 7, 2008
By

Vicor has introduced a number of new mid-power products to its families of pre-defined modules Maxi, Mini, and Micro DC-DC converters. These modules are well suited to the demands of military and aerospace environments, allowing designers to select standard products better tailored to their specific power and current requirements. Still incorporating Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS), these products’ inherent low noise greatly reduces the design effort and filtering costs required for power converters to meet various conducted emissions requirements, such as MIL-STD-461.

With these new offerings, Vicor can now provide an even greater variety of standard solutions, as shown in the table of available 24, 48, 300, and 375 Vin pre-defined modules (mid-power modules are listed in red):

Fully encapsulated, the products utilise a proprietary spin fill process that assures complete, void free encapsulation making them suitable for the most harsh environments. Two grades (H & M) are available with temperatures to -55°C operating and -65°C storage. H & M-Grade modules are qualified to the stringent environmental tests of MIL-STD-810 and MIL-STD-202 and undergo 100% Environment Stress Screening. The products are available with six different pin options and three baseplate options. They can be also be configured in any combination using Vicor’s PowerBench tools, which allow customers to configure an infinite array of custom module designs on-line, and verify them in real time.
