2n3055 voltage regulator
Variable Voltage Regulator 0-28V at 20A with LM317 and 2N3055
This is Variable Voltage Regulator 0-28V Size at 20A high current. By use IC LM317 be the control part Volt with VR1. The transistor 2N3055 x 5 amounts are wasp parallel. For help have current tall go up be 20A originally from at IC LM317 can give current get 1.5Amax only just. The detail is other. Please read at site source.
