This work presents the development of design methodologies for passive filters for static power converters connected to the network or operating in islanded mode. Methodologies for the design of inductive (L) filter and inductive-capacitive-inductive (LCL) filter for network connection and inductive-capacitive filter (LC) for converters operating as uninterruptible power supply (UPS) will be presented. For the L filter, methodologies based on the peak value of the current ripple in the inductor or on transfer functions of equivalent circuits are presented and aim to ensure that the total harmonic distortion of current (THDi) in the point of common connection does not exceed the values defined by specific rules. For the proposed methodology for the LCL filter, in addition to THDi, the resonance frequency, the damping coefficient of filter and the power factor in the point of common connection are design parameters to be met by the filter designed. The filter design methodology is based on equivalent circuit. The total harmonic distortion of voltage (THDv) and the damping coefficient are considered as design parameters. To corroborate the proposal, PSIM simulations are used and experimental results are also presented. |
