Every wind turbine generator will have an associated step-up transformer. Transformers have to withstand short circuit currents and they are generally tested for it. This paper presents a summary of the short circuit performance of wind turbine step-up transformers based on simulation and short ...
Almost all piezoelectric transformers are used for step-up-type transformers and they are seldom used for step-down-type transformer. We have developed a novel step-down piezoelectric transformer utilizing the piezoelectric transversal effect. As this transformer can be driven with lower frequency than...

We have an application where we go from a 5 mil overall stencil thickness and step up to 12 mils for a transformer (bell shaped pegs for leads). The stencil is etched. There is a 20-mil pitch IC (thus the 5 mil overall stencil thickness). We have had good success with this. ...

The voltage step-up ratio was continuously changed with increasing input voltage and load resistance. The output voltages and powers were increased with increasing input voltage at matching impedance. The temperature rise of the multilayer piezo stack transformer increased with increasing input voltage ...
DC motors draw power from deep cycle (DC) batteries. If you have a DC motor that is malfunctioning or drawing and bleeding power through the wires, there are tests that can be done to test the efficacy of the DC motor. This test can be done in your own workshop using simple hand too...
