There had been always complaint about the expensiveness of the thyristor APFC panels. Although we tried to convince the advantages of these panels, the cost was major concern for the customer. The contactor panel costs were more attractive considering capital investment. Although along the running years, the thyristor panels would save more money and would have cost less maintenance.
Sycon is solution provider. We worked on this problem and we came out with hybrid solution. In this, user can use advantages of both the types of panels i.e. Thyristor and Contactor type. We designed and supplied a relay which can be configured to use both contactor logic (slow but lower cost) and thyristor logic (higher cost but fast). User can configure any number of steps of total steps for contactor logic and remaining for thyristor logic. User can connect base or less frequently switched capacitors (heavy) with contactors and top-up or frequently switched capacitors (light) with thyristors. This would not only fetch a better power factor in dynamic conditions but also it will cost far less than all thyristor panel.
Few months back, one of our prestigious customers supplied this panel to its customer. We have been observing its results and those are very satisfactory.
Now I hope you would not lose any thyristor panel order due to its cost. We would love to share our experience with you to build panels to achieve better power factor. Because when we keep our customer’s power factor to unity, we not only save our nation’s energy but we save our mother earth from global warming also.
