Inverters typically include a feedback loop to regulate the output voltage and current and keep them from exceeding unsafe limits. In this system, the output AC mains voltage is first reduced to a correspondingly lower level before being sent to the control IC''s shut down pin.
This paper proposes a robust voltage control strategy for grid-forming (GFM) inverters in distribution networks to achieve power support and voltage optimization. Specifically, the GFM control approach primarily consists of a power synchronization loop, a voltage feedforward loop, and a current control loop.
The stepped down feedback voltage now follows the output AC and varies up/down accordingly, in a proportionate manner. The control ICs shut down circuitry comares and monitors this feedback signal with a fixed ference derived from the battery volatge of the inverter.
Although all of these inverters are well-designed and will produce the necessary 220 V or 120 V from a simple IC 555 configuration, they lack a built-in feedback system to ensure a steady output voltage. The diagram below shows how a regular IC 555 inverter may be changed into an improved inverter using a simple feedback loop control network.
