Shri Abhijit Sengupta (Sarma), EA AIR Siliguri has bagged 2nd prize in Best Technical Innovation category of Akashvani Annual Award - 2014 for the work - The Simulator for control card of FM PA GCEL and BEL Make.
The power control card of Power Amplifier is very important in respect of Fwd and Reflected Power control with immediate shut back to save the costly Bipolar transistor. This simulator give the necessary voltages to the different point of the card as per requirement so that the faulty card can repair without connecting it with PA which is very heavy in structure and difficult to work with. The simulator can adjust and tune the card for optimum condition of safe running of Power Amplifier so that a single person can repair and tune the faulty PA in the bench setup mode. The cost of the card is about Rs 250 without digital board. Only a good Multimeter is required for the above work. The same simulator has further developed to interface with PC for easy overshooting.
Congratulations from PB Parivar
