Method of regulating the voltage with step-up and inverting pulse converters

Inventia se refera la electrotehnica si este destinata pentru crearea unor surse si sisteme de alimentare cu energie electrica in baza regulatoarelor de tensiune prin impulsuri de tip de ridicare si inversare, si a convertizoarelor de tensiune analogice de transformare de functionare inversa. Procedeul de reglare a tensiunii cu convertizoare prin impulsuri de ridicare si inversare cu caracteristica de reglare neliniara si ambigua consta in formarea tensiunii de dirijare a modulatorului de durata a impulsurilor din contul transformarii neliniare a tensiunii de eroare, care se obtine prin compararea tensiunii sarcinii ca tensiunea inversa si tensiunii de sprijin. Caracteristica de reglare este liniarizata pe tot sectorul de lucru prin transformarea neliniara a tensiunii de eroare pe baza primei relatii din expresia caracteristicii de reglare dupa patru valori caracteristice ale regimului. Tensiunea inversa se formeaza din tensiunea sarcinii cu ajutorul deja al transformarii inverse neliniare in corespundere cu cea de-a doua relatie din expresia caracteristicii de reglare. The invention relates to electrical engineering and is designed to create electric power supply systems and sources based on voltage pulse regulators of step-up and inverting type and similar flyback transformer voltage converters.The method of regulating the voltage with step-up and inverting pulse converters with nonlinear and double-valued adjusting characteristic, with power voltageand relative loss valueconsists in the formation of the control voltageby means of a pulse-duration modulator at the expense of nonlinear error voltage conversion, obtained by comparing the feedback voltage, formed from the load voltage, and the reference voltage. The adjusting characteristicis linearized on the entire working area by means of the nonlinear error voltage converter based on the preset relations for the step-up and inverting pulse converters. The feedback voltageis formed from the load voltage by means of the nonlinear error voltage converter based on the preset relations for the step-up and inverting pulse converters.
