Abstract :
The paper presents an exact small-signal discrete-time model for digitally controlled DC-DC converters. The model, which is based on well-known approaches to discrete-time modeling and the standard Z-transform, takes into account modulator effects and delays in the control loop. The model is well suited for direct digital design of digital compensators
