PURPOSE:To control synchronously an analog operation system control device and a digital operation system control device, by providing an operation timing having a prescribed sampling period, to each operator, and also under the condition that operation of all the operators ends at every operation timing. CONSTITUTION:A current reference I0A is converted to an analog value i0A by a DC converter 6, is compared with a current detecting value iA, its difference DELTAi is operated and amplified by an analog operator 7A, also is converted to a digital signal by an A/D converter 10 by synchronizing with a timing signal T1A, and its data is inputted to a phase controller 11A and is held. In the same way, a current reference I0B is compared with a digital current value IB obtained through an A/D converter 9 as to its current detecting value iB, its difference DELTAIB is operated by an operator 7B, and its output data is inputted to a digital phase controller 11B and is held. A timing synchronizing circuit 12 outputs a timing signal T3, it is applied as a trigger signal simultaneously to the phase controllers 11A, 11B, and the held data is outputted as a phase control signal simultaneously. |
