            Abstract : 
A 50 A, ±225 V current regulated bipolar power supply has been developed to energize the solenoid coil in atom cooling experiment. The power supply operates on 415 V, 50 Hz three-phase ac mains. Topology used is a two-quadrant asymmetrical half-bridge operating at 25 kHz. The main feature of this power supply is its ability to generate fast rising and falling current profiles of peak amplitude 50 A in output inductive load with 1 ms rise and fall time. This paper presents power supply operation, design principles, peculiarities in fabrication and various results.
