LOCAL NETWORK WITH DIFFERENT ENERGY SOURCES INVERTER CHARGING AND DISCHARGE CONVERTER SYSTEM Russian patent published in 2018 - IPC H02J7/35 

FIELD: electronic equipment.

SUBSTANCE: invention relates to the field of industrial electronics and is intended for creation of the guaranteed uninterruptible power supply system for AC and DC consumers. System contains four sources of electricity (AC industrial network, array of photoelectric converters, gas / gasoline / diesel generator or wind generator, storage battery) and inverter charging and discharge converter system. Inverter charging and discharge converter system consists of a series of converters: bi-directional inverter operating synchronously and in parallel with the industrial AC network through the power distribution device, AC rectifier with power factor correction and tracking of the maximum power taken from the supplying it source (gas / gasoline / diesel fuel generator or wind generator), bidirectional three-port and unidirectional two-port high-frequency DC-DC converters, internal DC bus, controlling controller and information and control bus.

EFFECT: provision of guaranteed uninterrupted power supply to AC and DC consumers with reduced number of required for this purpose converters; increase in the entire system reliability and efficiency, increase in the AC and DC consumers uninterrupted operation time from the storage battery and increase in the photoelectric converters array energy use degree.
