Abstract: In an electronic circuit, a first circuit region is electrically connected to an input circuit region of an isolated switching power source, and a second circuit region is electrically connected to an output circuit region thereof. A driver of an IC is located in the second circuit region and drives a target device based on output power supplied to the second circuit region via the output circuit region from the isolated switching power source. A transferring module of the IC transfers a value of a parameter indicative of the output power from the second circuit region to the first circuit region while maintaining electrical isolation between the first and second circuit regions. An operating module of the IC performs on-off operations of a switching element to perform feedback control of the value of the parameter indicative of the output power to a target value.

Abstract: In a driver, a charging module stores negative charge on the gate of a switching element via a normal electrical path to charge the switching element upon a drive signal representing change of an on state to an off state. This shifts the on state of the switching element to the off state. An adjusting module changes a value of a parameter correlating with a charging rate of the switching element through the normal electrical path as a function of an input signal to the driver. The input signal represents a current flowing through the conductive path, a voltage across both ends of the conductive path, or a voltage at the gate. A disabling module disables the adjusting module from changing the value of the parameter if the drive signal represents the on state of the switching element.

Abstract: A driving apparatus for driving switching elements of a power conversion circuit. In the apparatus, a first determination unit determines whether or not a dead time that occurs immediately after a setting of discharge rate is changed is greater than the dead time assumed at the time of designing. When the dead time occurring immediately after the setting of discharge rate is changed is greater than the dead time assumed at the time of designing, a shift unit shifts in time at least one of transition to an OFF state of one of the upper-arm and lower-arm switching elements and transition to an ON state of the other of the upper-arm and lower-arm switching elements immediately after the transition to the OFF state so as to reduce a time difference between the transition to the OFF state and the transition to the ON state.

Abstract: In a driver, a charging module electrically charges the on-off control terminal of the switching element for turning on the switching element, and a limiting module performs a task of limiting a voltage at the on-off control terminal of the switching element by a predetermined voltage to thereby limit an increase of a current flowing between the input and output terminals of the switching element. A determining module determines whether the voltage at the on-off control terminal of the switching element deviates from the predetermined voltage while the limiting module is performing the limiting task. A correcting module corrects the voltage at the on-off control terminal of the switching element to be close to the predetermined voltage when it is determined that the voltage at the on-off control terminal of the switching element deviates from the predetermined voltage.
