Patent JP-H03102411-A (JP)
Title: Operating circuit for composite power supply
Inventor: TAKATO KENJI
IPC: H04Q1/28
Filed: 1989-09-18
Abstract: PURPOSE:To use a high voltage power supply to drive even a low voltage actuation circuit and to reduce the power consumption by providing a current bypass system to compensate the difference between a shared driving current and the driving current required by each low voltage actuation circuit. CONSTITUTION:No problem occurs as long as the driving currents I1, I2, I3... In can be set at I1=I2=I3... In (=I). However the currents I1 - In are actually different from each other. In this respect, a current bypass system 24 is provided to compensate the overs/shorts between a shared current I and the currents I1 - In. For instance, the current I1 - I2 is excessive when a low voltage actuation circuit (I1) 25 of the highest stage is switched to a low voltage actuation circuit (I2) 25 of the next stage. Thus the excessive current is set free to the system 24. As a result, the low voltage actuation circuits are driven with the high voltage for high voltage actuation circuits shared with each other. At the same time, a driving current is shared with each other among those low voltage actuation circuits. As a result, the power consumption is extremely reduced.

CONSTITUTION:A proportional electromagnetic control valve is provided with an opening degree detector 52 and pressure detectors 53, 54. A flow rate Q is calculated 55 on the basis of a difference among an opening degree X of a valve 5, an inlet pressure Pa and an outlet pressure Pb, and a control signal Qc is calculated 56 based on the flow rate Q and a flow rate command Qr. Another control signal Qp is calculated 57 on the basis of the outlet pressure Pb and a pressure command Pbr, and an opening area Aq(x) is calculated 61 based on the flow rate command Qr and the difference in pressure. Furthermore, another opening area Ap(x) is calculated 63 on the basis of a difference between the inlet pressure Pa and the pressure command Pbr and the flow rate Q, and then, the pressure command 62 Pbr is compared with the outlet pressure Pb. If Aq(x)> Ap(x) at the time of turning-in of a meter, the control signal Qp is selected PA 59. otherwise, the control signal Qc is selected 59. If Pd>Pbr at the time of turning-out of the meter, the control signal Qp is selected 59. Otherwise, the control signal Qc is selected 59 for outputting.
