Topology and Control for Second Harmonic Current Reduction in Two …
Aiming for high reliability, it is necessary to remove the electrolytic capacitor from a two-stage single-phase inverter. To enforce this, the flying capacitor of the flying-capacitor-clamped (FCC) boost three-level (TL) converter was employed to buffer the second harmonic current (SHC). In this article, the topology of FCC boost TL converter …

How to Install H-A-S Rotary Phase Conversion System
Since all the current for the system is obtained from single phase lines, and accounting for the losses of the converter; the amperage draw from the single phase lines will be approximately 2 times the total three phase motor nameplate amperages. Install the H-A-S Rotary according to the appropriate wiring diagram (Figure 1 or 2).
2. Install the rack or frame in which the capacitors are to be mounted. 3. Hoist each capacitor into position in the rack or frame using the capacitor''s hanger brackets. 4. Install each capacitor in the rack or frame so that heat from other equipment is minimal and air can circulate freely around each capacitor in the installation.
