Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

Whether you’re just getting into electronics or could use a refresher on some component or phenomenon, it’s hard to beat the training films made by the U.S. military. This 1965 overview of ...

A highly integrated step-up dc-dc converter and power management IC can start up and run from either plus or minus millivolt input sources, making it ideal for energy harvesting applications in which ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

Each turbine in a wind farm is equipped with a step-up transformer, which boosts (steps up) turbine generator output voltage from a few hundred volts to the collector system’s medium voltage ...
