This work is devoted to the development of a throttle modulator with a power of 10 kW at the peak point. A throttle modulator allows to pass the source current to a load directly, bypassing the active element, thereby reducing the power loss. Also, the modulation inductor eliminates the need for large filter capacities and inductors directly to power supplies, since the modulation inductor suppresses the ripple of the rectified voltage In the course of the work reviewed types of modulation, their advantages and disadvantages are considered. The best variation of the modulator implementation is selected, corresponding to the best efficiency and weight and size indicators. Produced the calculation and simulation of this scheme. A transistor is chosen as the active element, since the rejection of vacuum equipment significantly reduces the cost of production and maintenance, as well as the overall dimensions are reduced, and this, in turn, is one of the paramount tasks in the field of broadcasting in Russia. The result is a throttle modulator with an efficiency of 92%.
