Patent ID: 7773400

Claim:
An inverter driving circuit comprising: an input circuit for inputting an input signal in the form of a rectangular wave; a driver circuit for driving an inverter based on the input signal input through the input circuit; and a phase adjusting circuit which is provided upstream of the driver circuit and which delays at least either a rise or a fall of the input signal to adjust any difference between a pulse width of the input signal input to the driver circuit and a pulse width of a signal output from a switching element of the inverter driven by the driver circuit; wherein the phase adjusting circuit adjusts the delay time of at least either the rise or the fall of the input signal such that a delay time between a point when the input of the input signal to the driver circuit is started and a point when the switching element is turned on equals a delay time between a point when the input of the input signal to the driver circuit is stopped and a point when the switching element is turned off.
