Title:
SEMICONDUCTOR POWER CONVERTER
Document Type and Number:
Japanese Patent JPH06225539
Kind Code:
A
Abstract:
PURPOSE: To materialize the improvement of loss generated in a semiconductor power converter used for a power system or the like and the improvement of follow-up property to a command value at the same time.
CONSTITUTION: This converter is provided with inverters 4A-4C each composed of a control circuit 3, which operates an output command value, using the load current IL detected by CT1 for current detection and the power voltage VS detected by PT2 for detection of the voltage of a power source, and a plurality of semiconductor elements for power, which operate by the output command value operated in the control circuit 3 and are different in operation frequency area.
