of the U phase waveform, which has the opposite phase of the former. The U phase waveform output that
started from the “H” level keeps its level until the timer for setting dead time finishes outputting one-shot
pulses even though the three-phase output shift register’s content changes from “1” to “0” by the effect of
the one-shot pulses. When the timer for setting dead time finishes outputting one-shot pulses, “0” already

three-phase output shift register’s content changes from “0” to “1” as a result of the shift, the output level
changes from “L” to “H” without waiting for the timer for setting dead time to finish outputting one-shot
pulses. A U phase waveform is generated by these workings repeatedly. With the exception that the
three-phase output shift register on the U phase side is used, the workings in generating a U phase
