How to find the right rectifier
The schematic below should help the planning user to find out the right DC supply.
It is really simple to follow this schematic. It starts above at the right side with the definition of the process itself. This predertermines automatically which current and which voltage are necessary. All boundary parameters are parallelly mentioned on the left side.
As shown in another schematic, the degree of protection can be found. Also here, some fundamental reflections have to be made, e.g. concerning ambient conditions, fresh air supply or separate rooms.
From the cooling modes one version has to be selected. Here the output current serves as leading figure. If water as cooling mode is possible, this is recommended.
The most important decision is taken with the selection of the possible power control. From the start, switching mode power supplies have an uncritical ripple. When selecting the version with thyristor, once again the process has to be observed to decide upon the ripple.
From the environmental point of view it has to be considered, if oil still is the right cooling mode for the user. High efficiency and acceptable mains conduct have to be considered with regard to energy technics.
A high degree of utilization, e.g. at multi shift operation, requires a design which is easy to service to realize short down times in case of maintenance.
Before the rectifier can be defined, first the mode of operation has to be selected: pulse operation, polarity reverse operation, rectifier operation. Here it has to be observed, if e.g. a chrome rectifier with polarity reverse corrode/chrome is necessary. Or if for an ED coating rectifier further technical options have to be included.
Another important criterion for decisions is the budget available or the financial limit where technical points of view may fall through.
Independently from the schematic, the control methods have to be mentioned.
When selecting the optimum rectifier we are always prepared to offer sufficient support.
