Abstract
1. Способ регулирования мощности однофазного инвертора, обеспечивающий плавное регулирование мощности инвертора в каждой зоне регулирования за счет изменения длительности проводящего состояния полупроводниковых приборов инвертора, отличающийся тем, что регулируемая составляющая мощности инвертора суммируется с нерегулируемой составляющей мощности инвертора, для этого плавное регулирование мощности в пределах каждой зоны регулирования выполняется за счет изменения угла опережения выключения полупроводниковых приборов, тех плеч инвертора, которыми обеспечивается регулирование мощности в данной зоне, при переходе в другую зону регулирования мощности полупроводниковые приборы плеч инвертора, которые изменяли мощность инвертора в предыдущей зоне, работают с минимальными углами опережения выключения приборов с увеличением мощности инвертора, а с понижением мощности инвертора - угол опережения выключения приборов увеличивается до 180°, пульсации тока на входе инвертора снижаются с помощью накопителей электрической энергии большой емкости, реактора и обратного диода. ! 2. Устройство однофазного инвертора, состоящего из однофазного трансформатора, вторичная обмотка которого выполнена секционированной с последовательным соединением секций, к отпайкам секций подключены выходы плеч инвертора, отличающееся тем, что анодная группа плеч инвертора собрана на однооперационных приборах, катодная группа плеч инвертора собрана на двухоперационных приборах, вход инвертора через реактор соединен с шинами сети постоянного тока, параллельно входу инвертора соединены накопители электрической энергии большо1. A method of controlling the power of a single-phase inverter, providing smooth control of the inverter power in each regulation zone by changing the duration of the conductive state of the semiconductor devices of the inverter, characterized in that the adjustable component of the inverter power is summed with the unregulated component of the inverter power, for this smooth control of the power within each the regulation zone is carried out by changing the angle of advance of turning off the semiconductor devices, those shoulders the inverters, which provide power control in this zone, when moving to another power control zone, the semiconductor devices of the inverter arms, which changed the inverter power in the previous zone, operate with minimal lead-out angles with an increase in the inverter power, and with a decrease in the inverter power, the lead angle instrument shutdown increases to 180 °, current ripple at the inverter input is reduced with the help of high-capacity electric energy storage, a reactor and a reverse Oh yeah. ! 2. The device of a single-phase inverter, consisting of a single-phase transformer, the secondary winding of which is sectioned with a serial connection of the sections, the outputs of the inverter arms are connected to the branch tapers, characterized in that the anode group of the inverter arms is assembled on single-operation devices, the cathode group of the inverter arms is assembled on two-operation devices , the inverter input through the reactor is connected to the DC busbars, in parallel with the inverter input, electric energy storage devices are connected
