  • 400 Hz Power Supply For Aircraft - USA

    price: contact company for price

    Less iron is one reason that aircraft power systems are 400 Hz. - - mush

    less iron in transformers, motors, and generators as well as smaller

    filter capacitors in the electronics. That was a WW2 design tradeoff.

    Some of that may be different with modern electronics and 400Hz

    switching power supplies - - high frequency switching electronic

    supplies take that even further with kilohertz frequencies.

    Read on GoHz in summary about advantages and disadvantages about 400 Hz power supply. might it be i didn' t went to part about inverters. Anyways inverters and frequency converters are very expensive. By the way what about voltage drop if long DC lines, and if Powers to transmit are big what about reliability in case short fault.

    On the contrary, Bulk Power is transmitted through long High Voltage DC Transmission line. The saving in line losses more than compensate the cost of provision of Transformer, Rectifier etc. at both ends. Since DC Distribution voltage will have to be same as the DC generation voltage as DC voltage can not be stepped Up or Down, DC has very limited application for urban or rural Distribution power system. DC is widely used in Traction system mainly to achieve Speed control application for aircraft.

    That universal transformer emf equation quoted above by Victor indicates that if the frequency is increased to 400 Hz and nothing else changes, then the winding voltages can increase too. This agrees with keeping V/ Hz ratio constant. Is this correct?

    • Business Description: GoHz is a manufacturers based online shop in AC power supply industry to provide solutions for changing regular grid power frequency (50 Hz, 60 Hz), DC power source to adjustable frequency & voltage source. Solid state pure sine wave frequency converters, variable frequency drives, dc to ac power inverters etc. are for sale in affordable price on GoHz.

      The 2.2 kW AC Drive/Inverter is basically an AC to AC converter, perhaps for converting frequency from 50 Hz to 60 Hz or the other way round. And that you have an identical 2.2 kW AC Drive/Inverter and want to use it for driving a DC Motor.
