Using PWM allows precise current control in the windings ... coreless motors are estimated using a constant, linear DC power supply. A circuit diagram of a driving motor using a variable DC ...

A circuit breaker’s control wiring is also important ... Micro-ohmmeters, which are used to perform contact resistance tests, apply a DC current through the entire closed circuit breaker current path, ...

While passive precharge employs a power resistor to create an RC circuit that charges the capacitor asymptotically, active precharge can employ a switching converter with a buck topology that uses ...

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed. Designers have long used the gyrator circuit to create ...

Knowing this, Thibado's group built their circuit with two diodes for converting AC into a direct current (DC). With the diodes in opposition allowing the current to flow both ways, they provide ...
