METHOD FOR CONTROLLING CONSTANT VOLTAGE PULSE STABILIZER Russian patent published in 2005 - IPC

FIELD: electric engineering.

SUBSTANCE: for controlling constant voltage pulse stabilizer current value of stabilized voltage is measured, measured value is compared with constant support voltage, on basis of discordance signal by means of synchronization voltage of saw-like shape broad-pulse modulated signal is formed, used for controlling adjusting stabilizer element. Also, this signal is demodulated and received correction signal is added to discordance signal. When selecting correction signal transfer coefficient, static error value of voltage stabilization is corrected. It is possible to ensure equality of static error to zero by selecting transfer coefficient appropriately. Current control method is effective for different variants of direct voltage converters (of increasing, decreasing and inverting types) and different modes of their operation (as with continuous, as with discontinuous stabilizer throttle currents).

EFFECT: lesser static error of voltage stabilization in case of external interference (change of inlet voltage or load resistance, influence of non-ideal elements of stabilizer power circuit).
