As satellite missions become increasingly diverse, the power capacity of satellites continues
to increase. Accordingly, the weight and loss of the electrical power system of the satellite …

With rapid developments in the satellite data services market, the demand for low earth orbit
(LEO) satellites is increasing. Advancements in designing lightweight satellites are essential …

This article proposes a novel power processing unit (PPU) system architecture based on the
high-frequency alternating current (HFAC) bus for electric propulsion spacecraft. The …

The Japan Aerospace Exploration Agency (JAXA) has developed a power processing unit
(PPU) for a 6 kW Hall thruster system. The PPU is a candidate for future mission …

Recently, as the satellite data service market has grown significantly, satellite demand has
been rapidly increasing. Demand for geostationary satellites with weather observation …

The lifespan of a microsatellite depends on the adequate power obtained from its solar
array. Hence, it is important to monitor the degradation of the solar array in-orbit as uncertain …

The electrification of the transportation has shown a steady growth in the past decades. The
unmistakable advantages of the electronics in terms of control capabilities, precision and the …

In this article, we propose a two-stage factorized power architecture (FPA) dc–dc converter,
which caters to applications that require high efficiency, high power density, low ripple, and …

A fault-tolerant converter is widely used in high-reliability applications. To satisfy the high-
reliability requirements, fault tolerance is an essential feature and can be achieved by …

Abstract The Japan Aerospace Exploration Agency has developed a power processing unit
for a 6 kW Hall thruster, a candidate for propulsion systems for geostationary satellites. Hall …
