AB - In recent years there has been significant development of the element base of power electronics. The new circuit and design solutions have appeared, and the capabilities of the power supply systems of electrotechnological, radio-electronic and consumer devices have changed significantly. The current paper analyzes the methods of voltage regulation. The paper shows the method of obtaining an adjustable AC voltage, as well as the device for its implementation. The proposed method allows achieving a significant reduction in weight and size indicators of power supply units of various devices. The implementation of the concept is possible based on the method of modulating the output voltage with high-frequency pulses with varying duty cycle by means of pulsed electronics. Equa-tions for calculating the harmonic components of the Fourier series of a pulse se-quence for a half-sine curve are given. The most dynamically developing direction of power electronics is considered, which is connected with solving the problem of voltage regulation in controlled rectifiers and inverter devices.
