Title: Method for controlling reversible static power converter
Inventor: ENDO KAZUYA
IPC: H02M5/27
Filed: 1986-09-25
Abstract: PURPOSE:To shorten the selectively processing time of a converter group by deciding a method of selecting the converter group to be controlled from angle (phase) information for forming a current command value. CONSTITUTION:In a controlling method for a reversible static power converter such as a cycloconverter, a microcomputer calculates the winding current command values of phases by a current command value calculator 21. A current regulator 22 regulates the current by the current command value and the actual current value to control the phase of a thyristor. Further, a thyristor group selector 23 selects positive, negative thyristor groups in response to the polarity of each current command value. In this case, the angle A of the current command value is obtained by addition processors 21a, 21b from angle information and a constant B, the selector 23 selects the converter group to be controlled from the value, and judges whether it is converted or not. Thus, the selecting time of the converter group is shortened to accelerate the repetition period of the process.
