A method for calculating a switched inductive-capacitor generator has been developed that makes it possible to determine the voltages, currents, power, and efficiency of the generator taking into account the parameters of its elements in a pulse-frequency mode of power supply of an active-inductive load. To increase the efficiency of the generator, the voltage across the capacitor and the power of the generated current pulses in the load, it is necessary to increase the source voltage, the switching voltage of the dynistors (Shockley diodes), the switching frequency and duty cycle, the number of capacitor-charging periods, and the time constant of the inductive storage, as well as reduce the capacitance of the capacitor. A generator with a source voltage of up to 48 V and a current-pulse frequency in a load of 1 Hz can have a pulse energy of up to 12 kJ, an average power of up to 12 kW with an efficiency of up to 0.89 and a pulse power of up to 35 MW. It is possible to connect the generator to a source with an insufficient dc voltage level for charging the capacitor, with the voltage across the charged capacitor (639–3060 V) being able to be tens of times higher than the source voltage (12–48 V).
