DC STEP-UP REGULATOR Russian patent published in 2024 - IPC H02M3/156 

FIELD: converter equipment.

SUBSTANCE: invention relates to converter equipment and can be used in designing energy-efficient controlled DC converters. Device contains input, output and common terminals for connection of direct current source and load, respectively, one circuit consisting of series-connected charging diode, capacitor, throttle and charging switch, connected between input and common terminal, discharge switch connected between connection point of throttle and charging switch of chain and input terminal, discharge diode is connected between the connection point of the charging diode and the capacitor of the chain and the output terminal. An additional switch is introduced, connected between the connection point of the charging diode, the discharge diode, the chain capacitor and the connection point of the charge switch, discharge switch and throttle of the chain, smooth decrease (increase) of output voltage is carried out by changing the relative duration of the open state of the additional switch and the discharge switch during their serial switching, obtaining an output voltage greater than the doubled input voltage with only one resonant circuit and smooth adjustment of the output voltage.

EFFECT: increase in the voltage conversion coefficient is more than 2 with a smaller number of elements and the presence of one resonant circuit with the possibility of smooth adjustment of the output voltage in a wide range.
