Title:
SET INPUT CIRCUIT FOR THYRISTOR CONTROLLER
Document Type and Number:
Japanese Patent JPS57151265
Kind Code:
A
Abstract:
PURPOSE:To enable the supply of an effective set signal to arbitrary number of controllers with a single signal source by providing amplifiers for producing the set signals having the same output characteristics as an analog signal source and connecting in cascade with the set input of other set value input circuit the outputs of the respective amplifiers. CONSTITUTION:N pieces of SCR controllers 4l-4n provided with main circuits SCR 1l-1n between power sources 2l-1n and loads 3l-3n are respectively controlled at electric powers supplied to the loads 3l-3n via gate control circuits 5l-5n. The common set value applied as a target value to the control circuits 5l-5n is formed by the output voltage of an analog signal source 6, amplifiers 7l-7n are provided in the set value input circuit of the respective control circuits, and the outputs of the amplifiers are used as the power command signal of the respective power control amplifiers 8l-8n. The amplifiers 7l-7n has signal amplifying characteristic including the same output characteristics as the signal source with respect to the input from the signal source 6.
