Abstract
A PDP(Plasma Display Panel) module consists of a discharge panel, a SMPS for power supply, driving boards for panel control, and a logic board. Driving boards supply high voltage pulses to induce glow dischargein the PDP panel. The electrical pulses excite the circuit elements and subsequentlyacoustic noises. The main sources of the noise in the circuit are the transformer of SMPS and the power MOSFET of driving boards, and the heat sinks often amplify the noise level. (omitted)
