| Aspect | Fixed-Frequency SMC | Variable-Frequency SFC (converted from SMC) | |--------|---------------------|-----------------------------------------------| | Efficiency at heavy load | Good | Similar or slightly better (if ZVS/ZCS) | | Efficiency at light load | Poor (fixed switching losses) | Excellent (frequency drops, losses reduce) | | EMI signature | Narrowband peaks | Spread spectrum, lower peaks | | Control complexity | Simple | Moderate (VCO, frequency limiting, compensation) | | Magnetic design | Predictable | More challenging (wide frequency range) | | Transient response | Fast (high bandwidth possible) | Slower (frequency change takes cycles) |
