Abstract
A digital power supply and power supply controller are presented, including a voltage control loop and a current control loop, with a controller for pulse width modulating a switching power supply according to a voltage control loop duty cycle output or a current control loop duty cycle output, in which the controller selectively presets the voltage control loop duty cycle output to a predetermined value before switching from current loop control to voltage loop control and/or inhibits increase in a voltage loop integrator value during current loop control to mitigate voltage overshoot.
