ABSTRACT:
A driver circuit for driving a switching element in response to a driving signal from a driving signal generator includes an electrical isolation circuit for generating an electrically isolated signal from the driving signal in response to the driving signal; a first signal generator which receives the electrically isolated signal, and generates a first signal which level-changes from a second level to a third level in response to the level change of the electrically isolated signal from a first level to the second level; a second signal generator which receives the electrically isolated signal, and generates a second signal synchronous with the electrically isolated signal; a third signal generator which receives the signal from the first signal generator, and generates a third signal synchronous with the first signal; a fourth signal generator which receives the signals from the second and the third signal generators, and generates a fourth signal having a signal level equal to the sum of the second and the third signal levels, the generator including a metal oxide semiconductor field effect transistor.
