High Power Rectifiers and Control Upgrades for Mining Groups Worldwide
Chopper and Thyristor Rectifiers for Mining and Electrowinning
Dynapower is the world’s largest independent manufacturer of chopper and thyristor rectifiers for mining and electrowinning applications. With experience in power conversion since the commercialization of the thyristor, Dynapower has designs that cover all topologies. In addition to Dynapower chopper and thyristor rectifiers for mining, we also maintain exclusive rights for manufacturing and service of all products designed and manufactured by Rapid Power Technologies.
Dynapower’s mining chopper and thyristor rectifiers are engineered, designed, manufactured, and tested to internationally recognized standards including ANSI, IEEE, IEC, NEMA, UL, CSA, and JEC. Our design capabilities include the complete High Power Transformer Rectifier System – inclusive of fully integrated operator interfaces and control systems for a single unit or entire multi-unit SCADA network. With over 50 years of experience in high power conversion, Dynapower evaluates the impact of the rectifier system on the incoming power grid and designs power factor correction and harmonic filtering for the application to maximize system efficiency. Using the latest rectifier technologies, application engineers can recommend the optimum rectifier configuration for any mining project.
Upgrading your high power rectifier system with the latest digital controls is a cost-effective alternative to full system replacement or costly maintenance. Control upgrades can significantly extend the operating life of your existing high power rectifier system and provide improved performance, safety and reliability.
WHO WORKS WITH US
OUR MINING SOLUTIONS
Dynapower designs and manufacturers high power rectifiers for large applications. These are available in 6, 12, 18 and 24 pulse sets with higher order combined systems available. Each multi-pulse arrangement is in an ANSI configuration that is selected for the voltage/current values of the application. The multi-pulse criteria is selected to reduce the supply side harmonic content, reduce output DC ripple, and provide improved regulation.
Dynapower recognizes that purchasing new high power rectifiers can be a costly proposition for any enterprise. That is why we offer control upgrades to legacy high power rectifiers to improve their efficiency, uptime, and extend the life of the rectifier itself. In addition to providing digital control upgrades to Dynapower and Rapid high power rectifiers, Dynapower offers system evaluations and control upgrades for all major manufacturers of high power rectifiers.
Dynapower leads the industry with over 500 MWs of commercial and utility-scale energy storage inverters, DC converters and fully-integrated energy storage systems installed worldwide. Our fully-integrated solutions feature Dynapower energy storage inverters coupled with lithium ion batteries in 2, 4 and 6-hour configurations. Energy storage can be implemented with or without solar to reduce energy costs and provide critical backup power.
