1. Phaseback DC Choke A Patented Product Complete Voltage Smoothing AC Harmonic Filter for DC Circuits of All Sizes Presented by Applied Energy LLC William Hinton, Director of Engineering

2. What is ThePhaseback DC Choke? • An electromagnetic AC Filter • Reduces AC noise from a DC circuit at all frequencies and all harmonics • While unique in design, the DC Choke shares many common applications in various form factors

3. What is ThePhaseback DC Choke? • The Phaseback DC Choke is not a power source, rectifier or output circuit • It is a filter which cancels AC current in a DC circuit using the AC electromagnetic field • Provides benefits not available in other chokes

4. What distinguishes thePhaseback DC Choke from others? • Phaseback DC Choke is a revolutionary product that takes advantage of a property called mutual counter-electromagnetic inductance. • Unlike typical DC Chokes, it uses a combination of seriesand parallel opposing electromagnetic forces • Because Phaseback’s method of filtration does not rely solely on the eddy-current and hysteresis losses in the core for current control, its AC current reduction does not heat up the iron core; instead, it applies a counter-electromagnetic force • The simplest benefit: Our design reduces AC noise at a rate exceeding 4 times a similarly sized traditional choke or inductor

5. How did the Phaseback DC Choke Come About? • Its original design intent was to: • Remove electrical noise within the DC link of a Variable Frequency Drive • Prevent equipment from feeding AC noise back into the power system • Instead of dispersing electrical noise in the form of heat, Phaseback DC Choke simply dissipates the noise by beating it against itself, resulting in an electromagnetic suppression of AC noise. • In applying the Phaseback DC Choke, we discovered an increase in overall system energy efficiency.

6. Traditional DC Choke: Limited Range of Effectiveness • This graph depicts the effective range of filtering for a competitor’s choke • Must be tuned to filter specific frequencies • Typically only filters two or three frequencies Percent Total Harmonic Distortion at Various Harmonics

7. Phaseback DC Choke: A Full-Range Harmonic Filter Thanks to its unique design, the Phaseback DC Choke is not constrained by the limitations of typical chokes It filters AC noise at all frequencies Shown at left: The Phaseback DC Choke removes every harmonic frequency above DC through 296,829 Hz

8. Phaseback DC Choke: Immediate Applications • Allows for higher speed processors and memory • Decrease computer crashes by regulating exact voltages to the CPU and components • Extend hard drive, memory, CPU, fans, and overall computer life • Reduce power consumption & heat in cell phones, laptops, and other battery powered consumer devices • Advanced, precise voltage regulation for green energy systems such as solar and wind turbines • Protection of satellites and spacecraft from solar flares and issues caused by AC noise • Prevents power problems experienced by DC marine vessels and large power generation facilities • Reduces power loss of high-voltage DC systems, improving efficiency and range • Can be used in AC circuits to prevent “cogging” when installed after a VFD or Servo Drive • Can be designed in for clean control power for a VFD and PLC to prevent and control lockup • Can be designed in or added to the DC link within high voltage grid tie substations

9. Phaseback DC Choke: Immediate Applications • In industrial VFDs, will minimize harmonics generated back onto the line, a serious issue most industries deal with on a daily basis. • In UPS systems, it will remove the AC which causes damage and shortens battery life, from the DC link and on power systems which supply DC to various numbers of individual loads. • DC crane drives and controls for safer, smoother operation • Reduces the combined total of the AC noise from the power system, decreasing power loss and allowing additional devices to be powered from the power supply. • Electric cars for smoother operation and increased reliability • Battery charger for electric cars to remove the AC from affecting the DC power

10. Other Applications • The Phaseback DcChoke is perfectly scalable • Allows the same basic design and function for thousands of applications • From nano-technology to DC power systems in large ocean vessels • MRI machines could benefit from a design which no longer requires special cooling systems • Could help protect space probes and orbiting vessels from power spikes and uncontrolled power issues far from home

11. Some of our R&D applications include: • Increase CPU frequency limits and reduce heat • Using a secondary coil to recover the EM fields and convert them to usable energy • Adding a toroidal core for miniature circuits, explore effects of various materials • Explore the heat-less magnetic generation effects for MRIs and other EM devices • Uses in Nano-Technology
