METHOD OF CONTROLLING CHARGER WITH PULSE OPERATING PRINCIPLE Russian patent published in 2024 - IPC H02J7/34 

FIELD: converter technology.

SUBSTANCE: invention can be used to control a charger with a pulse operating principle, which, during the charging of a battery, ensures voltage stabilization at the output of the primary energy source to which the charger is connected. At each period T of operation of the charger in the vicinity of time points t₀, t₁, t₂ and t_3, controlled electronic keys are switched. The moment of time t₀ coincides with the beginning of the period T, and the moment of time t₁ is formed according to the principle of pulse-width modulation as a function of the integral of the input voltage mismatch signal and the dynamic component of the input voltage U_in of the charger. Moments of time t₂ and t₃ depend on the moment of time t₁, the inductance of the inductor L, the input U_in and output U_out voltages of the charger, the moment of time t_k at which the inductor current takes a negative value, some negative current I₀ of the inductor and the coefficient K_px and are calculated using the formulas: t₂ =t₁+Δ t, where Δt is a fixed time interval selected based on the condition: 0≤Δ t<T and t₃ =t_K-LI₀/U_out.

EFFECT: low amplitude and duration of transient processes and voltage astaticism at the output of the primary energy source and at the load connected in parallel to the primary energy source.
