Zusammenfassung:A pulse width modulated current control method and system architecture may achieve the high performance of an advanced current control for full-bridge stages, in terms of accuracy, error, speed, and frequency response, but with a reduced complexity in terms of used analog circuits, being comparable with that of an elementary peak current control. The only analog blocks used may be a current sense transducer, i.e. a series resistor or a sense-FET, and a comparator for the current sensing while the rest of the control circuitry is digital.
