Is IPCs Universal Power Converter AC-link the same AC-Link used by Princeton Power Systems (PPS)?
A. No, the Universal Power Converter (UPC) technology is completely different, with the link being truly AC, having no DC offset in voltage or current. Additionally, our link is dynamic, always oscillating, while the PPS link is quasi-static, in that it may be stopped intra-cycle in order to reduce power output. The UPC AC-link reduces power output instead by reducing the charge transfer on each power cycle. Also, the UPC AC-link produces two power transfers for each link cycle, whereas the PPS AC-link has only one power transfer for each link cycle. Other important features of the UPC converter lacking in the PPS AC-link include full buck-boost capability, true soft switching, input-output isolation, and much higher minimum link frequencies which allow for greatly reduced I/O filtering requirements, which improves efficiency and reduces weight and costs.
