Isolated Point of Load Modules (iPOLs)
Overview
Spacecraft power systems are utilizing highly distributed bus voltages as payload power demands continue to increase. Frontgrade DC-to-DC Converters and Power Distribution Modules (PDMs) offer the industry’s best end-to-end efficiency from the satellite bus down to the point of load.
Frontgrade PDMs are highly efficient, flexible, scalable, and lightweight — all in a small footprint. Our PDM family consists of Input Regulator Modules (IRMs) and Isolated Point of Load Modules (iPOLs) that make up a power conversion system.
The IRM provides a regulated intermediate voltage to the iPOL, which can be set to adjust to load condition by utilizing the adaptive loop feature between the IRM and iPOL. The iPOLs are isolated, unregulated DC-to-DC converters that divide down the intermediate bus voltage provided by the IRM. These PDMs can generate an adjustable voltage and are compliant to MIL-PRF-38534.
Isolated Point of Load Modules (iPOLs)
Frontgrade iPOL Modules excel at speed, density and efficiency to meet the demands of advanced power applications while providing isolation from input to output. These units deliver up to 50 amps of current with unprecedented efficiency and the smallest footprint in the industry for a radiation hardened by design Point of Load Converter. When used with our IRM family, they form a complete DC-to-DC converter subsystem offering. Designed for low voltage, high current digital systems; sensitive low noise high speed ADC and DAC circuits; and RF power applications.
