“…1. The gener ator is constructed according to the scheme developed by (Barannik et al, 2010a(Barannik et al, , 2010b(Barannik et al, , 2013, which has now become a classical one. The output inverter (OUTI), which generates current with sinusoidal shape and arbitrary amplitude and temperature in the antenna, i.e., power transmission line (PTL), is the basic element of the generator.…”

“…The output inverter (OUTI), which generates current with sinusoidal shape and arbitrary amplitude and temperature in the antenna, i.e., power transmission line (PTL), is the basic element of the generator. The generation prin ciple of output sinusoidal current is based on the pulse width modulation method and is described in detail in (Tereshchenko et al, 2009;Barannik et al, 2010a). The current shape generated in the antenna using pulse width modulation may be changed from sinusoidal to an arbitrary one (meander, triangle), if necessary.…”

“…The authors' experience of designing high power ELF-SLF generators (Barannik et al, 2010a) and examples of implementation of similar devices by other manufacturers show that an increase in dynamic losses in key elements of the IN and thermal losses in the high frequency transformer is among the disad vantages of transformation at high frequency. These losses lower the technical and economic parameters of the device being developed if its power exceeds 50 kW.…”

The structure and a possible practical application of the portable generator with extremely and super low frequency (ELF-SLF) range (0.1-200 Hz) and power of 2 kW are described. The generator is designed for deep sounding of the Earth's crust for the purposes of mineral exploration and electromagnetic monitoring of source zones of earthquakes in seismically active regions. Computational and theoretical works, as well as numerical simulation for optimizing the generator's parameters and element base, are car ried out. The main constructive elements of the generator, namely, the power factor corrector, the driver con trol circuit for power transistors, the inverter of the high frequency decoupling converter, the multichannel pulse power converter, the output inverter, and etc., are consistently described. The generator's weight does not exceed 10 kg, and, therefore, the generator may be easily delivered to a testing site using any kind of trans port, including planes. The generator is powered by the single phase network with a voltage of 220 V. The full scale testing of the generator is performed at the territory of the Yamalo Nenets autonomous okrug via the connection to the high voltage transmission line Urengoi-Pangody with a length of 114 km. The maximum current in the line is 12 A. The maximum distance of reliable signal recording is 110 km.Keywords: portable generator, electromagnetic sounding, extremely and super low frequency range, seismi cally active zone, industrial power transmission line
