The MPC is a bidirectional converter that uses an energy storage element (such as a battery or capacitor) and a high-speed switch (HSS) to eliminate voltage dips experienced by a facility. The MPC is an optional standby energy source.
With the MPC, correct power will be supplied at all times without missing the slightest drop in power. MPC prevents damage to critical equipment and plant shutdowns that can occur due to momentary voltage dips.

Energy Storage Device
Storage Battery |
Capable of power supply 10 seconds to several minutes as a compensator for momentary voltage dips. Also capable of coping with repeated momentary voltage dips and power failure. |
Electric Double Layer Capacitor
|
Momentary voltage dips compensation time is generally from one to several seconds. Provides longer life than storage batteries. |
