Description
Summary:A boost converter and a system of energy transfer at a high voltage (up to 1100 V) developed for an “Energy-2” generator 200 kW in power are described. This generator is intended for solving the problems of precision monitoring of the electromagnetic depth of the Earth’s crust at seismoactive regions with an aim to search for earthquake forerunners. High voltage allows taking off the total generator’s power on transmitting antennas with high resistance (7 Ω and higher) within a wide frequency range (0.1–200 Hz) as well as on low-resistance antennas (lower than 0.7 Ω) at high frequencies (greater than 20 Hz). Modern Russian and foreign literature on the problem of developing transformers and rectifiers of the generator’s power circuit, responsible for generation of powerful low-frequency electromagnetic signals, is reviewed. Theoretical research and numerical simulation of the “Energy-2” generator’s power circuit are performed and the element base of the latter is optimized. Based on the developed documentation of all components, radiators and a system of forced ventilation have been made. The proposed generator-measuring complex has no analogs in world practice and can be used for solving a wide range of fundamental and applied problems.
