Minimum Reactive Power Filter Design for High - PPGEE
... In many works, passive sinusoidal filters come out as good alternative to reduce the system harmonic content. The inherently low switching frequency of high power converters, limited from about 500 to 1000 Hz, complicates filter design, which generally results in large filter elements. Besides, due ...

Compared with using a fixed frequency bandpass filter, a tunable filter may also reduce the number of down-converting stages required in an agile receiver by allowing a greater down-conversion step to be made. Rejection of interfering signals that, for example, may occur at the receiver image freque ...
