Abstract
A driving device and driving method for controlling electric power to a load is provided. The driving device controls switching operations of switching elements by setting a first duration in which electric power is supplied to the load and by setting a second duration in which the load is floated without electric power. The driving device feeds back an output signal outputted from output terminals of the load, receives an input signal, and compares the fed back output signal with the input signal to detect an error. The driving device also generates an error suppression signal to correct the detected error and controls the switching operation of the switching elements based on the error suppression signal.
