High Power Chopper Rectifiers
幸运农场Dynapower’s high power chopper rectifiers have been designed for processes that require large voltages and currents. Chopper technology offers several key benefits over standard thyristor technology. The diode rectification used in chopper rectifiers results in a high power factor, eliminating the need for power factor correction equipment. Diode rectification also results in reduced harmonic effects, reducing the need for harmonic line filters. Ripple is also reduced by the use of IGBTs. With a constant ripple over the entire operating range (typically <2%), ripple filters are no longer needed.
幸运农场Chopper rectifiers are a modular approach to rectification. This modular approach results in simplified transformer designs. It also makes maintenance easy if a module fails. Simply replace the module and get your unit running again in no time. Simplified transformer designs paired with the elimination of power factor correction, equipment, harmonic filters, and ripple filters, the efficiency of chopper rectifiers are unbeatable.
Compared to their standard thyristor rectifier counterparts, chopper rectifiers also offer space and cost savings. With the reduction of additional equipment and simplified designs, less materials are required for each unit. This also reduces the overall size of the unit. This makes chopper rectifiers easier to install, getting your production up and running faster than ever before.
