Abstract: A control unit is for a bridge circuit. The control unit may include a signal generator configured to generate first and second periodic drive signals for the bridge circuit, and determine a switch-on duration of the first and second periodic drive signals based upon a first digital data value having a first resolution. The control unit may include a controller configured to receive a second digital data value having a second resolution. The second resolution may be greater than the first resolution. The controller may be configured to generate the first digital data value so that, over periods of the first and second periodic drive signals, the first digital data value corresponds to an average of the second digital data value.
