摘要： Control signals for operating power converter switching elements (5l-56, 3l-36) are created using one-­chip microcomputers (l0, ll). Pulse patterns required to supply the control signals and their generating timings are previously created and scheduled in pairs. When the times when the control signals are to be supplied to the switching elements have actually come, those control signals are successively output.
