    Is Sepic converter good for 200W,input voltage from(100-1000vdc) and output is 200vdc and output current is 1a

    I would go w/ a buck-boost if isolation is not required. For isolated (off-line) converters, a forward converter would be my choice for these specs. Please be very careful. A thousand volts is never to be taken lightly.

    It is possible, but relatively impractical. A SEPIC converter is one of several buck/boost topologies. I've tried one a couple of times, and always found them to be a bit quirky compared to other designs. But the big problem you'll have is the 9:1 input voltage range. That's a lot to ask from whatever the magnetic structure is. Standard parts and app notes probably won't work without a lot of adjusting.

    Nice rig. How do you like the hammered ride, and how do you keep from chipping it when going for the tom?

    I love the hammered ride, K custom model. I just hit the tom and avoid the ride, sometimes I end up hitting it anyway. Also FWIW, this K custom ride model can also serve as a crash. Not a true crash, as its weight makes it slow to respond. But if you want a very loud, and sustained crash, it works great. I really love the "K" series of cymbals, dark shimmering sound. I also have a lot of "A" series as well. They are brighter sounding. Thanks for the interest.
