A new sustainer with primary sided integrated of DC/DC converter and energy recovery circuit for AC-PDP

A new Sustainer with Primary sided Integration of DC/DC converter and Energy Recovery circuit (SPIDER) is proposed. The proposed circuit operates as a DC/DC converter during address period and energy recovery circuit during sustain period. Therefore, the conventional three electronic circuits composed of the power supply, X-driver, and Y-driver can be reduced to one circuit. As a result, it has desirable advantages such as a simple structure, less mass, fewer devices and cost reduction. Moreover, since the Zero Voltage Switching (ZVS) of all power switches can be guaranteed, a switching loss can be considerably reduced. To confirm the operation, validity, and features of the proposed circuit, experimental results from a prototype for 42-inch PDP are presented.
