A METHOD OF CONTROLLING A SWITCHED MODE POWER SUPPLY AND CONTROLLER THEREFOR |
摘要 |
A controller for an SMPS is disclosed. The controller applies a frequency jitter to the SMPS to reduce Electromagnetic Interference (EMI) and/or audible noise. A second input variable is multiplied by a correlated jitter signal, in order to compensate the output power for the frequency jitter. A corresponding method is also disclosed. Since the jitter compensation occurs within the controller, the method is particularly suitable for controllers operating under different control modes for different output powers (or other output criteria). The multiplicative compensation is applicable across a wide range of converter types. |
