FIELD: electricity. ^ SUBSTANCE: invention is related generator of control pulses, for instance, in switching stabilizer. Technical result consists in the fact that without reduction of duration of synchronizing pulse, which serves as single interval of pulse generator time, width-pulse control is possible, at that the duration of pulse is changed in move out times, which are shorter than the single time interval. The duration of Ton_s signal of accurate division of pulse duration Vs, which comes from the processor of signal digital processing (PSDP) (17), is changed by duration of synchronizing pulse Tclk depending on the deviations of output voltage Vo. The device of time interval control (18), which receives signal of accurate division of pulse duration Vs, shapes in control signal Vd changing segments (30, 31) for change of duration of setting signal Vg change for shorter value of time DeltaTd, than duration of synchronizing pulse Tclk. As a result, the division of duration of setting signal Vg is improved, being better, than duration of synchronizing pulse Tclk, i.e. time resolution of the PSDP (17). ^ EFFECT: receiving the possibility of width-pulse control without reduction of synchronizing pulse duration. ^ 7 cl, 10 dwg |
