Alternating Current

Alternating Current as a power source, what is it and what are the advantages? Example of an AC sine wave Alternating Current is the power you get out of a wall socket at home and at work.  It is often abbreviated as AC. The reason it’s called Alternating Current is the voltage is constantly changing Alternating Current

Direct Current

Direct Current for Power A Direct Current power source provides a constant voltage as opposed to Alternating Current which supplies an oscillating voltage.  All types of batteries are direct current such as alkaline, lithium, lead acid and others.  Other sources of direct current include electronic supplies like the 5V from a USB charger and many Direct Current

Shunt Regulation

A shunt regulator is a device that clamps the power supply voltage at a certain level to prevent the bus from exceeding rated values. Benefit Shunt regulators help to avoid nuisance shutdowns due to regeneration ADVANCED Motion Controls’ Capabilities Many drive models have built-in shunt regulators or shunt circuits A wide selection of external shunt Shunt Regulation


Boost, or step-up converters convert DC voltages from one level to a higher level. Benefits The maximum speed of a system is often limited by the available bus voltage; boost provides an easy way to get more speed without having to redesign the power system or add more cells to a battery system Implemented in Boost
