Low-pressure bleed air plus electrical cooling cuts fuel use, removes precoolers, and reduces thermal load in aircraft air conditioning.

Ground/flight switching connects stored electrical power to the thrust reverser only on the ground, avoiding oversized generators and in-flight deployment.

Paired battery packs use controlled bus disconnects to improve aircraft charging efficiency, fault isolation, and emergency shutdown safety.

Progressive device re-coupling after a network fault helps pinpoint and isolate faulted loads without shutting down healthy sections.

Distributed MMU and PMU monitoring detects battery faults and triggers high-voltage disconnect to prevent eVTOL pack damage.

Precharged and voltage-balanced capacitors deliver rapid shaft assist for aircraft maneuvers while reducing electrical losses, wear, and weight.

Three CAN bus bundles balance bandwidth and wiring length while preserving minimum acceptable flight control after any two bus failures.

Parallel distribution buses with switchable contactors isolate faults and keep aircraft electrical loads powered without extra battery mass.

A modular bracket with adjustable beam attachments fits multiple under-seat power box models and orientations while reducing seat-specific parts.

Adjusting motor current phase by flight and abnormal state boosts eVTOL torque without raising current, improving propulsion efficiency.

Multiple isolated battery circuits keep thrust balanced around the aircraft center of gravity during propulsion or battery failures.

Converter control drives negative sequence current to zero to bypass line faults, limiting heating and failures without shaft cutting.

An override switch relaxes battery power-reduction triggers to extend engine bus supply and reduce false trips in critical flight modes.

Sensor-based control limits propulsion current when aircraft high-voltage wiring nears its temperature limit, avoiding heavier oversized cables.

Selectable TVS shunting lets an aircraft DC bus adjust suppression thresholds during overvoltage events to protect onboard components.

Alternating parallel battery packs keeps voltage gaps within a threshold, avoiding lithium metal battery damage from low-rate discharge and high-rate charging.

Symmetrically arranged inverter and buck switches cancel out-of-phase common-mode signals, cutting EMI and reducing bulky filter needs.

Fast fault protection blocks the aircraft power converter, then opens the contactor to isolate the DC bus and prevent high-current damage.

Dynamic bus bar reference switching stabilizes hybrid aircraft voltage regulation across changing power flows and long cable runs.

Reconfigurable AC/AC conversion and shaft switching let hybrid turbomachines supply aircraft AC loads while using both high- and low-pressure shafts.

Independent light units use rechargeable capacitors to cut aircraft emergency lighting weight, wiring, and battery maintenance.

Cumulative electrical energy and switching time reveal real contactor wear, avoiding count-based replacement and reducing maintenance cost.

Heavy cooling hardware is shifted offboard while fluid circulation keeps batteries within charge-safe temperatures and helps prevent thermal runaway.

Controllable eVTOL power buses shed noncritical loads in emergency modes to preserve battery reserve for propulsion, avionics, and control.

Physical separation and parallel cell strings let one battery architecture supply HV propulsion and LV loads without converter-driven propagation.
