The energy storage capacitor is used to power the DC/DC converter during an event of failure of power on a field power bus. A capacitor of value typically more than 1 mF is used to provide power to PLC CPU during failure.
Reliable Startup with Large and Unknown Capacitive Loads (Rev. A) Industrial equipment such as a Programmable Logic Controller (PLC) need large capacitors for storing energy to provide backup time for storing critical information before equipment shutdown.
The PLC CPU needs energy storage to provide a backup for storing critical information in case of loss of power. The energy storage is either provided by a battery or a large capacitor. A large capacitor is preferred over a battery for energy storage due to its lower cost. Figure 1-1 provides a block diagram for the PLC CPU. Figure 1-1.
A PLC power supply is a device or module responsible for converting high-voltage alternating current (AC) from the main power source into low-voltage direct current (DC) suitable for a PLC system. It typically steps down the voltage, rectifies it to DC, and stabilizes it for consistent delivery to the PLC.
The backup capacitor C16 needs to source power to load in case of an input supply failure. The single supply inverting Schmitt trigger U3 continuously compares the input for a threshold
