PROBLEM TO BE SOLVED: To provide a current control and drive circuit which reduces load current pulses and electromagnetic interference.SOLUTION: The current control and drive circuit according to the present invention includes: an equivalent impedance 1100; a main load 1101; an inductive voltage-dividing resistance element 1102; a DC electronic control unit 1103; a voltage measuring instrument 1104; a current measuring instrument 1105; a flywheel diode 1106; and an isolation diode 1107. When a voltage measured by the voltage measuring instrument 1104 or a current measured by the current measuring instrument 1105 is lower than a predetermined value, the DC electronic control unit 1103 is operated to increase a current flowing through the main load 1101. When the voltage measured by the voltage measuring instrument 1104 or the current measured by the current measuring instrument 1105 is higher than the predetermined value, the DC electronic control unit 1103 is controlled to reduce the current flowing through the main load. |
