Abstract: FIELD: electrical energy generation without consuming raw materials. SUBSTANCE: method depending on implementation of so-called single-pulse effect implying that any electric current or voltage pulse has unlimited store of electrical energy involves setting desired composition of amplitude-spectrum harmonics using factors of expansion of periodic functions into inverse-transform Fourier series to synthesize periodic signal; the latter is synthesized, its parameters are determined, zones of excess potential in periodic signal being synthesized are recorded, if any, whereupon DC voltage of external power supply is chosen according to averaged value of periodic signal. Then DC voltage is converted into periodic pulse signal with chosen averaged voltage value , desired composition of amplitude spectrum harmonics, and recorded zones of excess potential; only after that voltages having desired composition of amplitude-spectrum harmonics with recorded zones of excess potential are filtered off, each harmonic is rectified, rectified voltage of each harmonic is added, and DC voltage obtained in this way is used as power supply for various users, external power supply is turned off, and then new power supply is switched over to off-line operation. Pulse signals of different waveforms with pulse-to- period ratio 2 or video pulses of different waveforms with higher pulse-to-period ratio and homogeneous composition of amplitude-spectrum harmonics, or radio pulses of different waveforms with higher pulse-to-period ratio and homogeneous composition of amplitude-spectrum harmonics in immediate proximity of carrier frequency may be used in some cases as periodic signal. In particular cases, DC voltage of external power supply may be converted into two sine-wave signals at different multiple frequencies, and pulse signal with maximal ratio of 2 is shaped across analog divider for all harmonics of amplitude spectrum of signal generated.
