High voltage high power density dc dc converter for capacitor charging applications.

This paper presents a dc dc converter topology for charging high voltage bulk capacitors for pulsed load applications. Tdk lambda americas manufactures a broad range of high voltage programmable capacitor charging and ac dc power supplies. A 48 v to 24 v 20 a voltage divider with a power density of 4000 w in3 the ltc7820 is a fixed ratio high voltage high power switched capacitor controller that yields small and cost effective solutions for high power nonisolated intermediate bus applications with fault protection. By jian li jeff zhang ya liu and marvin macairan download pdf the power density of a dc to dc converter is generally limited by bulky magnetic components especially in applications where the input and output voltages are relatively high.

When compared with other capacitors with similar. Xp power is committed to being a leading provider of power solutions including ac dc power supplies and dc dc converters high voltage power supplies and rf power supplies. The dsf series comes with 17 different value voltage combinations and offers a capacitance ranging from 1 5f farad to 600f with voltage ratings from 3 0 wvdc for a single component to 6 wvdc for a dual pack device. The topology is a compact variant of the flyback converter with completely.

Thus a significant effort has been devoted to the design of suitable capacitor charging power supplies for these applications. The tps548d22 is a 40 a synchronous buck converter in a powerstack package suitable for storage telecom or similar digital high density pol applications. Our products include the ale series constant current capacitor charging supplies that are specifically designed to repetitively charge capacitors in pulse discharge circuit such as modulators and pulse forming networks. Here we describe some of this ongoing.

This converter is capable of efficiently transferring power from 30 v input to a capacitor charging from 0 v to 6 kv. The topology is a compact variant of the flyback converter with completely soft switching variable frequency control and optimal magnetics design. Cornell dubilier has announced the introduction of the dsf series of supercapacitors under the illinois capacitor brand. The system of consists of a multiple buck converters supplied by a bus voltage.

System level to increase the power density of power management systems in portable applications. A key element of these compact pulsed power systems is the high voltage power supply that typically charges a capacitive storage element. A typical architecture of a power management system for a battery powered applications is shown in fig 6. The buck converters provide well.
