I need a high speed switching power supply circuit that can switch at 100K Hz while passing 50A at 12V.

It doesn't have to be a power supply per say. It can be a circuit that turns a power supply output on and off at 100K Hz but can pass 50A of current. It needs to take my TTL PWM signal and use that signal to turn the power supply output on/off acting like a high side switch. Please direct me to a company that can design and build this circuit/box or at least supply a circuit design to accomplish this.

you must think the field of industry that uses such and higher frequencies . . . ? radars , telecom , welding , induction heaters , energy distribution
it's below kW though . . . maybe some tools and motors -- i'm not too at home with any - so - just a thought
