Keeping the noise down: Converter and inverter output filtering Most modern power conversion topologies use switched-mode techniques for highest efficiency and smallest size and cost. Inevitably, switching noise is produced and output filters are required to minimise EMI and provide reliable operation of the power converter and load. In the latest post from our inverter and drive design series Adam Chidley looks at the effects of noise on power conversion design and some of the filtering techniques that can be used to counter it. |
