San jose, calif, 20 march 2013 advanced power electronics corp in san jose, calif, is introducing the ape2902 high-efficiency vfm step-up dc-dc converter for small low-input voltage or battery. These battery-powered systems typically employ an embedded digital signal processor (dsp) to achieve maximum processing power when handling both supplies require high-efficiency dc-to-dc converters that are designed for battery applications the regulator that supplies the core voltage. Advanced power-conversion topologies achieve both wide input voltage range and high efficiency, enabling modular dc-dc converters to satisfy military power bus requirements and simplify power electronic-system design modern military vehicles and aircraft are packed with sensitive electronics. In battery-powered converters, the peak inductor current is important because it directly affects battery life and parasitic losses it partly depends on the average load current, which varies with the regulator topology, the control circuitry, and whether the inductor current is continuous.
