Ideal Power was formed to develop and commercialize the Company's patented Power Packet Switching Architecture™ (PPSA). PPSA is an entirely new approach to electronic power converters. It has a 100% indirect power transfer compared to direct power transfer from conventional power converters. All the energy runs through, and is temporarily stored in, a high-frequency AC link consisting of an inductor and capacitor. Since the input and output are never directly connected together, this novel current modulation technique provides circuit isolation without the size, weight, cost, and efficiency loss of a transformer. It also provides buck/boost voltage conversion, bi-directional power transfer, and multiport applications with any combination of independently-controlled AC and DC power ports.
 

In PV inverter applications, the PPSA delivers weight and efficiency benefits of a transformer-less inverter, while supporting grounded PV arrays, which are the de facto U.S. standard.
 
Other unique attributes of the Power Packet Switching Architecture™ include:
  • Non-resonant soft-switching dramatically reduces electrical and thermal stresses on power switches (silicon IGBTs).
  • High AC link frequency utilizes compact inductor, eliminating bulk capacitors and further improving system reliability.
  • Precise intra-cycle current management minimizes the need for output filtering.
  • Bi-directional AC switches (shown in blue) minimize conduction losses, delivering high-efficiency power transfer in all modes of operation.
