  • Unidirectional matrix converter with regeneration system
    Patent number: 10135353
    Abstract: An AC-to-AC matrix converter includes a controlled rectifier input stage, an inverter output stage, and a regenerative unit. The controlled rectifier input stage is electrically connected to a power source and configured to convert AC input power from the power source into DC power. The controlled rectifier input stage may be unidirectional. The inverter output stage is electrically connected to a load and operates to convert the DC power into AC output power, which is then fed into the load. The regenerative unit is electrically connected to the inverter output stage and operates control energy generated by the load in a regenerative mode within the inverter output stage. The controlled rectifier input stage may be isolated from the inverter output stage in the regenerative mode.

  • ACTIVE POWER FACTOR CORRECTION FOR AIRCRAFT POWER SYSTEM HARMONIC MITIGATION
    Publication number: 20150145325
    Abstract: Active power factor correction can be used to reduce input harmonics in an aircraft power distribution system. In an embodiment, one or more power factor correction (PFC) units can be placed in a power distribution system to profile an input signal. Each PFC unit can include a converter, such as an AC-DC converter, and can be placed in the power system bus on the input side of the load. In an embodiment, a PFC unit can include a boost rectifier topology with active power factor correction for harmonics elimination.
