METHOD FOR DC VOLTAGE PULSE CONVERSION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC H02M3/335 H02M3/325 H02M3/337 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering and its can be used in converters of direct voltage to alternating voltage - inverter-HM and voltage regulator-HM for self-sustained power supply systems and electric drives for perspective aerospace flight vehicles with predominantly or completely electric drive equipment. According to the method of direct voltage pulse conversion energy from DC power source is supplied permanently to double-capacitor rack connected to this source. By means of pulse control of two control keys at the first stage of each period of high-frequency periodic dosing energy is accumulated in a dosing choke by its connection to one of two capacitors in the rack through one closed key while the second key is open. At the second stage the energy accumulated at the first stage is transmitted to the other capacitor in the rack at open state of the keys from the dosing choke through one or two rectifier diodes. Energy accumulated in the capacitors of the rack and dosing choke and energy of the power supply source is transmitted on permanent base to AC load through bidirectional circuit between medium terminals of the power supply source and capacitance rack with periodic change of voltage value and polarity for the load at alternating half-cycles of low-frequency periodic process. At the stage of each period when load voltage increases the energy accumulated in the first capacitor of the capacitance rack and power supply source is transmitted by doses to the second capacitor and load. At the stage of the same period when load voltage decreases or remains unchanged the energy from the second capacitor of the capacitance rack and power supply source is transmitted by doses to the first capacitor and load.

EFFECT: enhancement of functionalities - receipt of output voltage with arbitrarily assigned periodic-continuous form, in particular, sinusoidal.
