IEEE TRANSACTIONS ON POWER ELECTRONICS‚ VOL. 22‚ NO. 1‚ JANUARY 2007 Modulation-Based Harmonic Elimination Jason R. Wells‚ Member‚ IEEE‚ Xin Geng‚ Student Member‚ IEEE‚ Patrick L. Chapman‚ Senior Member‚ IEEE‚ Philip T. Krein‚ Fellow‚ IEEE‚ and Brett M. Nee‚ Student Member‚ IEEE Abstract—A modulation-based method for generating pulse waveforms with selective harmonic elimination is proposed. Harmonic elimination‚ traditionally digital‚ is shown to be achievable by comparison of a sine wave

Hybrid Electric Vehicles (HEV) usually need power conditioning‚ typically rectification which uses non linear devices‚ that produces a non-sinusoidal line current due to their non- linear input characteristics. The reduction of line current harmonics for enhancing the efficiency is Power Factor Correction. For active power factor topologies‚ there exist bridged and bridgeless power converter circuits. This paper focuses on a bridgeless Interleaved Boost Converter (IBC) for shaping the line

Harmonic Hearing Co. Case Recommendation Under the two circumstances presented‚ I recommend that Harriet Burns and Richard Irvine should finance the purchase of Harmonic Hearing Co. through the deal proposed by the private equity firm‚ Comet Capital. This proposal best aligns with Burns and Irvine’s goal to select an option that offers the “best combination of cost‚ expected return of their ownership interest and financial flexibility.” To evaluate the two alternatives‚ a comparison

One World: Motion Topic: Write an article that explores how the Physics of Motion is (or can be) used to solve a specific problem in a local or global context. Millions of people everywhere around the world make use of the principles of motion to travel up and down quickly within a tall building. The use of elevators has been around since ancient medieval times since then has grown from being powered by a hoist and winder to electric and hydraulic motors1. An elevator

Translational motion Translational motion is the aspect in which a body moves from a specific point to the next. This can be in terms of objects‚ molecules or atoms. This kind of motion normally takes place in a straight line for instance bullet which is fired by a gun. The object in motion does not change by turning on its axis for it travels in a straight line. Any slight change or rotation can cause the object to change direction in general making it not move toward the specified direction.
