Description

  The present invention relates to a current control and drive circuit, and more particularly to a current control and drive circuit that shunts through a voltage dividing load.

Current limiting control is applied to a load driven by a conventional AC or DC power source, and current limiting is normally performed by controlling conduction or shut-off for an on / off device connected in series with the load. .
The current control and drive circuit is disclosed in, for example, Patent Document 1.

JP 2002-291103 A

However, since the current change is relatively large when the on / off control is performed, when the load is an illuminating lamp, the lamp becomes brighter or darker. When the PWM control voltage is directly applied to the load current, the comparison is performed. It is a disadvantage that large electromagnetic interference is formed.
In order to solve the above problems, an object of the present invention is to provide a current control and drive circuit that reduces load current pulses and electromagnetic interference.

  In order to achieve the above object, a current control and drive circuit according to the present invention includes an equivalent impedance, a main load, a divided load, an electric energy control device, a voltage measurement device, and a current measurement device. The electric energy control device is connected in parallel to the voltage dividing load, and controls the flow of the current passing through the voltage dividing load. Due to the shunt control method of the electric energy control device, the electric energy control device increases or decreases the current passing through the voltage dividing load, and changes only the resistance at both ends of the voltage dividing load connected in parallel to the electric energy control device. . As a result, the load current pulse is relatively small. Therefore, in the case of an illumination lamp, the load changes relatively brightly or darkly, and a relatively small electromagnetic interference is formed.
