Regulation characteristics of the DC-DC converter with digital current-injected control circuit

A new digital current-injected control circuit is proposed for a DC-DC converter, in which the output voltage and the reactor current are employed to perform the pulse width modulated (PWM) control of the switch. The regulation characteristics of this digitally controlled DC-DC converter are analyzed theoretically and experimentally. As a result, the design criterion of the digital control circuit can be obtained.<
