Title:
OUTPUT VOLTAGE CONTROL CIRCUIT OF INVERTER
Document Type and Number:
Japanese Patent JPS60237889
Kind Code:
A
Abstract:
PURPOSE:To shorten the time of regulating operation and to simplify the operation by regulating a torque in the low frequency of an inverter with single regulating means. CONSTITUTION:A standard voltage characteristic A and a low torque voltage characteristic B are obtained from switching a changeover switch 12. Since the lower output voltage of two calculators 1, 2 is always output in an OR operation, characteristic indicated by a characteristic curve C is obtained when an input voltage Vi is lower than Va. Than, a torque boost is regulated by regulating the bias via a variable resistor 13 to output as an output voltage Vout along the curve C output when the input voltage Vin is low.
