As an example, a land based airport that has 50Hz or 60Hz absolutely need a Hz rotary or static converter. This is the same for ships as their typical power is V at another frequency, so in this case, they need the converter to change voltage and frequency. Skip to content. Do you use a sig gen hooked to the input of this unit to vary the frequency? Your spec needed was V 2A VA. Those are linear. My friend's company has a larger unit that is otherwise similar to that, it's about an 8U rack cabinet and weighs a few hundred pounds.
Inside is a huge transformer and a linear amplifier made from banks of 2N transistors on a huge heatsink. Great for testing magnetics, but I wouldn't want to use it to power something long term. We have such old beauties at work too - mainly to test performances of active PFC circuitry on a very clean power supply with low distortion.
I do not know about the large unit, the smaller ones are I think VA units, and are I think 3U units. Not sure off hand the part no. I work on flight simulators and we use hz v converters I was able to track down 1 of them but its an aircraft part so im sure its stupid expensive but im betting we have a non aircraft version, if not I can always open it up and take some pictures and get you some details.
Im back in Thursday afternoon ill keep trying. I know for a fact it wont like 60hz Trying 60Hz on a Hz equipment is downright You can damage it! Most of the tech uses transformers in the power supplies, that will saturate at low frequency and burn out. If I was to build a frequency converter for this purpose, I'd just use a PWM modulated H-bridge, with suitable low pass filtering network.
I'd say that there is nothing that fancy in such frequency converter. Sign In. Most airplanes have either generators or alternators that produce power. Rather than using the same 50 or 60 Hz frequency as standard wall outlets, though, airplanes use Hz frequency power.
Why do so many airplanes use Hz power exactly? Electrical systems play a key role in the function of modern-day airplanes. All airplanes contain a myriad of electrical devices and components, which require power to function.
As previously mentioned, airplanes can generate power either by generators or alternators. Airplanes can operate on a range of different power frequencies, some of which are alternating current AC , whereas others are direct current DC.
With that said, most airplanes have an electrical system that specifically uses Hz. That, of course, is substantially higher than the 50 or 60 Hz frequency used in standard wall outlets. The reason given to me was that the Hz allowed for smaller components capacitors and inductors and for smoother AC to DC conversion. The advantage of high-frequency alternators is that they require fewer copper coils in order to generate the necessary electrical current.
This reduction in material allows the alternator to become much smaller such that it takes up less space and weighs much less than it would otherwise. A higher frequency also increases loss of power over long distances, so using it on long transmission lines would be a bad idea.
