Title:
CONTROLLER FOR CONVERTER
Document Type and Number:
Japanese Patent JPH0684651
Kind Code:
A
Abstract:
PURPOSE: To perform anhysteresis prevention control coordinated with load current control while preventing anhysteresis for a transformer connected with a converter such as an inverter.
CONSTITUTION: The converter controller comprises a control means 19 for operating proportional gains K1 and K2 for controlling the primary and secondary currents of a transformer 5, respectively, according to formulas; K1=R1-α02 L/R2K2=L1R2/L3+(L2+L3)α02L/(R2L3)--2α02L/L3, R2=R2T+R2LL2=L2T+L2 LL=L1L2+L1L3+L2L3 using preset circuit constants and control response proportional constant α0 of a main circuit 5A thus controlling the primary and secondary currents of the transformer.
