The growing call for lower emissions and carbon neutrality has created an increased focus on more electric aircraft (MEA), as aircraft manufacturers look to satisfy the needs of travelers while achieving environmental goals being mandated around the world. 

The evolution to MEA changes the way most pneumatic, hydraulic, and mechnical systems are implemented. Whether it’s a more electric aircraft with jet engines, a hybrid electric or a fully electric aircraft, mechanically-driven pumps for hydraulics, pneumatics, oil, and fuel may one day be replaced with fully electric components for everything including flight surface controls, environmental systems, and braking.

To serve this emerging market, Parker has designed a product line of Intelligent Power Management Systems.

Developing innovative solutions for new power demands

Migration from hydraulic and pneumatic energy to electric energy requires improved power-handling capability and efficiency.  System voltages for more electric aircraft (MEA) could climb from 28VDC and 115VAC to upwards of 1,000VDC. This power will be delivered by a complex combination of generators and batteries and requires a highly advanced and flexible electrical distribution system capable of managing system needs.

 

The typical electrical interfaces on today’s aircraft consist of mechanical relays and contactors, which are not fast enough to prevent fault propagation. This drives a need for an effective solution for high voltage, high-power buses with enhanced capability.  To answer this call, Parker' Fluid Systems Division has developed a modular solid-state power controller (SSPC) for use as a standalone unit that is an electronic replacement for a relay or contactor.

Utilizing new semiconductor technology and modular architecture

Parker Aerospace is a world leader in the research, development, manufacturing, integration, flight qualification and sustainment of Intelligent Power Management Systems (IPMS), Motor Controllers (MC), Electronic Controllers (EC), Power and Frequency Converters (PFC), and Energy Storage (ES) for aerospace commercial and military applications.

 

Parker engineers have designed systems that replace power distribution electro-mechanical contactors with solid state power controllers (SSPC), supporting adaptive, controllable and energy efficient architectures for future air vehicles and propulsion systems.

 

An SiC-based SSPC offers the potential to significantly outperform current state-of-the art electro-mechanical contactor technology as well as the Si-based SSPC technology used on aerospace vehicles today.

An individual SSPC can be programmed and coordinated with other SSPCs to provide staggered power on/off configurations when used in a multi-channel configuration. Power sequencing, source and load isolation, power routing, and bi-directional flow for battery charge/discharge, can all be configured in the same SSEDU. Voltage, current, temperature and other performance and fault data is available for each SSPC.

The Parker Aerospace modular SSPC design provides benefits beyond the technical specifications.
