Custom Power Supply

I need a power supply for the load of 10KW, which will feed it with the alternative currency, but by pulses of 2 KHz. The power in the load will be regulated by regulating the duty cycle of pulses. Control pulses can be generated by PC or programmable controller, as the power in the load should vary depending on the time/date. Can you propose a diagram for such a device? What switching power elements to use - say power transistors, MOSFET SSR, whatever? Maybe exist ready blocks, which can be used to assemble such a device?
