Abstract
Способ управления вентильным электроприводом, состоящий в том, что в электроприводе, содержащем электродвигатель с ротором на постоянных магнитах, статорные обмотки которого подсоединены к выводам переменного тока мостового инвертора, выводами постоянного тока, подключенного к источнику электропитания и емкостному накопителю, в режиме движения и режиме торможения блок управления ключами инвертора формирует сигналы, изменяющиеся в соответствии с законами движения и соответственно торможения с помощью высокочастотной модуляции в функции величины сигнала движения либо торможения, причем в режиме торможения в один полупериод частоты (Т) высокочастотной модуляции на время t≤Т/2, где t - величина сигнала торможения, одновременно открывают все полупроводниковые ключи инвертора, присоединенные к положительному выводу источника электропитания, а в следующем полупериоде частоты на такое же время открывают все полупроводниковые ключи, присоединенные к отрицательному выводу источника электропитания, при этом на остальное время все ключи закрывают. A method for controlling a valve electric drive, consisting in the fact that in an electric drive containing an electric motor with a permanent magnet rotor, the stator windings of which are connected to the AC terminals of a bridge inverter, DC outputs connected to a power supply and a capacitive storage, in the driving mode and in the braking mode the inverter key control unit generates signals that change in accordance with the laws of motion and, accordingly, braking with the help of high-frequency modulation as a function of the magnitude of the motion or braking signal, and in the braking mode in one half-cycle of the frequency (T) of high-frequency modulation for a time t≤T / 2, where t is the value of the braking signal, simultaneously open all the semiconductor switches of the inverter connected to the positive terminal of the power supply, and in the next half-cycle of the frequency, all semiconductor switches connected to the negative terminal of the power supply are opened for the same time I, while for the rest of the time, all keys are closed.
