A new low-cost energy-recovery circuit for a plasma display panel

PDP을 위한 새로운 저가형 에너지 회수 회로

A new low-cost energy-recovery circuit (ERC) for a plasma display panel (PDP) is proposed. It has two auxiliary switches clamped on a half sustain voltage, and inductor currents are built up before the PDP is charged and -discharged. Therefore, it features a low cost, fully charged/discharged PDP, zero voltage switching (ZVS), low electromagnetic interference (EMI), low current stress, no severe voltage notch, and high energy-recovery capability.
