I have four stage Darlington power Transistor module:
With this charactrictic. Type No:QM1000HA-24B
Manf.:MITSUBISHI ELECTRIC
High power for switching use
Max.Ratings
c=7Kw Ic=1000Amp. Tj=-40....150C hfe=750
Vcex=1000volte
Can I use? this power Transistor module for liner application With pre regulator system
for limet power dissipation.
If this type of power Transistor module no good for this application.pleas help me what type I can use?
circuit info.:
Liner series regulator for Magnet DC power supply
Voltage source:60Vdc constant
Voltage out put: 0...........50V dc Liner varible & fast Response to load change&low out put current ripple
Current OUT PUT:0......200Amp. Liner varible and no harmonic& Distroiton
Load:0.25ohm Indective
Power dissipation:3KW
With water cooling system
Flow:20 GPM with water pump
