PROBLEM TO BE SOLVED: To provide a circuit element driving device which can reduce wiring necessary for driving a plurality of circuit elements without decreasing an instantaneous maximum voltage which can be applied to the circuit elements. SOLUTION: The circuit element driving device is provided with a control unit 7 and a driving part 6. The control unit 7 receives the n-number of first command values u1, u2, u3 for generating voltages to be applied to the n-number (n is an integer of at least 2) of circuit elements 2, 3, 4 having two terminals, and generates and outputs the p-number (p is an integer of at least (n+1) and less than 2n) of second command values α, r1, r2, r3, on the basis of the n- number of the first command values u1, u2, u3. The driving part 6 generates and outputs the p-number of driving voltages Vcom , V1, V2, V3 on the basis of the p-number of the second command values. At least one from among the p-number of the driving voltages is a voltage changing on the basis of at least one out of the first command values and applied in common to the respective position terminals of at least two of the circuit elements. |
