In an apparatus for generating complementary first and second pulse width modulation signals (U-PWM, /U-PWM), a signal generating circuit (101, 11U, 21U, 31U, 41U, 101A, 101B, 101C, 51U) generates a first signal for causing the first pulse width signal to switch from an ON level to an OFF level, a second signal for causing the first pulse width signal to switch from the OFF level to the ON level, a third signal for causing the second pulse width signal to switch from the ON level to the OFF level, and a fourth signal for causing the second pulse width signal to switch from the OFF level to the ON level. A control circuit (12, 22, 32, 42, 52) sets a first dead time (d1) between the first and fourth signals and a second time (d2) between the third and second signals individually.
