Soft start / stop interfaces are required whenever an
electrical engine is powered through a rather sensitive device.
Especially when starting an electrical engine by applying
nominal voltage to its terminals, a huge current spike
appears in the circuit. If, for example, the above-mentioned
engine is powered from an UPS or AVR, this sudden current
spike can easily trigger the overload protection in the UPS/
AVR, which halts the UPS into error state and shuts down the
electrical power. Even if the engine is powered directly from
the power socket, this spike can cause the electrical fuse to go
o. To avoid this risk, the soft start module interface powers
the engine gradually, starting from a much lower voltage
and increasing gradually to the nominal voltage in an user-
dened period of time. The area of usability is very large,
from any domestic appliances that use electrical engines
(central heating unit, etc.) to water pumps, wood gaters etc.
