Analog Control Techniques for DC-DC Converters (Buck Converters):
- Voltage Mode Modulator
- Feedback-driven control of duty cycle based on output voltage.
- Current Mode Modulator
- Control loop senses output current for better stability and transient response.
- Constant On-Time Control
- Simplifies design with fixed on-time, achieving fast transient response.
- Adaptive Constant On-Time Control
- Adjusts on-time dynamically for improved performance under variable conditions.
- Poles and Zeros Analysis
- Detailed examination of transfer function to ensure stability and optimal control loop behavior.
