Harmonica compensation technologies are used to suppress harmonic current based on the harm of harmonic current. The operational principles and characteristics of passive and shunt active power filters are introduced. Test results of different harmonic power filters applied in radar power systems are given. The test results show that harmonic power filters can effectively suppress harmonic current produced by radar power supply system.
