    Dear friends,

    I have a problem please guide me, :confused:
    I have two different DC sources, one with (V=300 v & I=1 mA) and another (V=0.7 v & I=50 A). As you see one source is a good voltage supplier and another is the current well. I am looking for circuit that I can use it with these two power simultaneously so that our power consumer that need the (V=200 v & I=30 A) can use it. For example, can I use these in a transistor circuit as VEE and VCC or in other circuits?

    There's no free lunch. The total power from your two supplies is 300V x 1ma = 0.3W plus 0.7V x 50A = 35W or 35.3W. So even with 100% conversion efficiency the most you could get at 200V would be 35.3W / 200V = 176.5mA, slightly short of your 30A requirement. :rolleyes:
