Abstract
A current drive device control circuit for controlling drive currents that flow in a plurality of current drive devices serially connected to a constant current power source is characterized by comprising a plurality of bypass circuits parallely connected to each of the plurality of the current drive devices, wherein each of the plurality of the bypass circuits controls a bypass current flowing in own circuit thereof and the drive currents of the current drive devices corresponding to the bypass circuits whose bypass currents are controlled.
Claims21
A current drive device control circuit for controlling drive currents which flow in a plurality of current drive devices serially connected to a constant current power source, the circuit comprising:
- a plurality of bypass circuits parallely connected to each of said plurality of the current drive devices,
- wherein each of said plurality of the bypass circuits controls a bypass current flowing in own circuit thereof and the drive currents of said current drive devices corresponding to the bypass circuits whose bypass currents are controlled.
A current drive device control circuit for controlling drive currents which flow in a plurality of current drive devices serially connected to a constant current power source, the circuit comprising:
- a plurality of bypass circuits parallely connected to each of said plurality of the current drive devices;
- a plurality of current detection means for detecting any of a bypass current flowing in each of said plurality of the bypass circuits and a drive current flowing in each of said plurality of the current drive devices;
- a plurality of comparative control means for generating a control signal by comparing a detection signal corresponding to a current detected by each of said plurality of the current detection means with a reference signal for deciding a reference level of said drive current;
- and
- a current control means for controlling the bypass current which flows in a corresponding bypass circuit out of said plurality of the bypass circuits, based on a level of the control signal output by each of said plurality of the comparative control means.
