In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

Prior knowledge needed: ECEA 5700 Introduction to Power Electronics, ECEA 5701 Converter Circuits, ECEA 5702 Converter ... and a graded Quiz on average current-mode control of dc-dc converters. Final ...

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 ...

The low output voltage level of the analog sensor and the long distance to the control room together constitute significant system design challenges. Here are clues on how to solve them. The 4-20 mA ...

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 ...

Understand how to specify the proper AC or DC motor for a machine design ... of motor equations for voltage, current, torque and speed. Implement the motor and accompanying rotary sensor into a motor ...

the current in DC circuits flows only in one direction. The electrons, which make up the electric charge, go from the point of low potential to the point of high potential as the direct current runs.
