The MIL-COTS Bus Converter Module (BCM) is a high efficiency (>96%), Sine Amplitude Converter (SAC) operating from MIL-STD-704E/F 270 V and delivering an isolated 30.0 – 41.25 V or 38.3 – 55.0 V. The BCM is suitable for use with the MIL-COTS PRM™ Regulator and VTM™ Current Multiplier, and is ideal for aircraft distributed power applications.
The bus converter achieves a power density of >919 W/in3 in a V•I Chip™ package compatible with standard pick-and-place and surface-mount assembly processes. Due to its high conversion efficiency and safe operating temperature range, the module does not require a discrete heat sink in typical applications. Low junction-to-case and junction-to-lead thermal impedances assure low junction temperatures and long life in the harshest environments.
