Surge Correction
Continuous Voltage Regulation
◆Load Voltage Compensation

〓 Features 〓

The YIY-AVC is an inverter based system that protects sensitive industrial and commercial loads from voltage disturbances.Providing fast,accurate voltage sag and surge correction as well as continuous voltage regulation and load voltage compensation.The YIY-AVC has been optimally designed to provide equipment immunity from power quality events on the supply network.

〓 Working Principle 〓

▶The YIY-AVC consists of two converters that are not on the current path between the load and the utility. Instead,the corrective voltage injection is achieved by means of a transformer winding between the utility and the sensitive load.This configuration results in a very efficient and effective method to provide voltage correction with reduced risk of negative impacts on the load.

▶The YIY-AVC requires no batteries as it draws the additional energy required during sag to make up the correction voltage from the utility supply.With no ongoing maintenance costs typically associated with batteries the cost of ownership for YIY-AVC systems is very small.

▶Furthermore,the YIY-AVC contains a redundant internal bypass system that,in the event of overload or internal fault condition,ensures that the load is continued to be supplied from the utility.

〓 Operational Detail 〓

The following diagrams show the YIY-AVC operation when a utility disturbance occurs, and operation of the internal bypass.

Utility Voltage Close to Nominal Level
When the utility voltage is close to nominal level, i.e. typical utility supply conditions without sags or surges, the PCS100 AVC-40 is only adding small corrections for utility voltage unbalance or load induced voltage variation.

Internal Bypass Operation
In the case of an overload or internal fault condition the internal bypass circuit will shunt the inverter side of the Injection Transformer, bypassing the inverter and effectively providing a direct connection from the utility supply to the output, without interruption to the load.

Utility Disturbance Occurs
When the utility voltage deviates from nominal or the set point due to a power quality event, the inverter will inject a correcting voltage via the Injection Transformer.The correcting voltage level based on the disturbance level and the enemy needed for correction is sourced from the utility via the PCS100 AVC-40 rectifier.

Diagrams on the left show cases with utility voltage below and above nominal level.
