The supply of uninterruptible power can be applied to many areas where
continuous operation is highly prioritized.
The application of uninterruptible power for motor operation is facilitated
using a frequency converter. Direct current operated frequency converters can
be applied directly to the power reserve which removes the need for additional
Batteries have long constituted the power reserve but advancements in
the development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to high
Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Uneven
voltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell’s 56V module is created
and constitutes the power reserve in the simulations.
The discharge simulation shows a significant current that could damage
the system. A current limiting transistor is introduced in the circuit to provide
a safer course of discharge. The result of the simulations confirms that the
application of ultracapacitors in uninterruptible power for motor operation is
