Abstract

The invention relates to the field of electrical engineering, namely to the electric power supply systems using solar batteries and is meant for the operation and test of the power consumption extremal regulation in the maximum power regime of the solar batteries.The solar battery simulator is made in the form of a power supply unit, including two quasi-resonant energy converters (1, 2) with similar short-circuit currents, the first (1) of which is made with the load characteristic close to the rectangular one, and the second (2) - with the load characteristic close to a slanting line. The outputs of the energy converters (1, 2) are connected in series.Each quasi-resonant energy converter (1, 2) comprises a commutation pulse generator, the outputs of which are connected to the bases of the transistors of the half-bridge support, the collector of the first transistor of which is connected to two resonance throttles, connected in series, the output of which is connected to one lead of the power supply, to the second lead of which it is connected the emitter of the second transistor of the half-bridge support. The energy converter (1, 2) also comprises a resonance capacitor, one lead of which is connected to the average lead of the half-bridge support, and the second, through the primary winding of the output transformer with load - to the common lead of the resonance throttles.The transistors of the half-bridge support of each energy converter (1, 2) are connected to the commutation pulse generators so that the Tc pulse repetition period of the first energy converter (1) may comply with the condition:Tc ≥ 2T0,where T0 is the period of proper oscillations specified by the resonance throttle and resonance capacitor, and the pulse repetition period of the second energy converter (2) may comply with the condition:2T0 ≥ Tc ≥ T0.
