Hello,
I have designed simple circuit of Pass Transistor with 2X TIP35C along with LM317 Because i need to control huge current. As Per Data Sheet TIP35C can easily handle around 25A each TIP35C Transistor. I have paralleled the 2X TIP35C and using 24Volt 15Amp power supply. While giving output its 50% of total power. Input SMPS AC Line shows 115 Watt and output Generated on the Controlled DC Side is just 55 Watt... ? 50% Energy loss ?
what should i do to reduce the losses ?

Please tell me...why 50% loss ? Does it depends on wire thickness ? i have used 3 Sq MM Thick wires and not more than 30 CM long...Thanks
