High Power Rectifiers and Control Upgrades for Mining Groups Worldwide

Mining Thyristor & Chopper Rectifiers

Dynapower is the world’s largest independent manufacturer of mining thyristor & chopper rectifiers. With experience in power conversion since the commercialization of the thyristor, Dynapower has designs that cover all topologies. In addition to Dynapower mining thyristor & chopper rectifiers, we also maintain exclusive rights for manufacturing and service of all products designed & manufactured by Rapid Power Technologies.

Dynapower’s mining thyristor & chopper rectifiers are engineered, designed, manufactured and tested to internationally recognized standards including ANSI, IEEE, IEC, NEMA, UL, CSA, JEC, etc. 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 particular application to maximize system efficiency. With the latest techniques in all rectifier technologies, application engineers can recommend the optimum rectifier configuration for any mining project.

Dynapower also recognizes that maintaining the efficiency of your long-lasting rectifiers is crucial to the bottom line. That is why we offer digital control upgrades for any high power rectifier system so our metals manufacturing partners can maximize the return on their initial capital equipment investment.

OUR MINING SOLUTIONS

IGBT/Thyristor

Dynapower designs and manufacturers mining thyristor & chopper rectifiers as well as fast switching IGBT chopper 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 are selected to reduce the supply side harmonic content, reduce output DC ripple, and provide improved regulation.

Control Upgrades

Dynapower recognizes that upgrading equipment can be a costly proposition for any mining enterprise that is why we offer control upgrades to legacy 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 mining thyristor & chopper rectifiers, Dynapower offers system evaluations and control upgrades for all major manufacturers of high power rectifiers.
