Lifetime is an important performance factor in the reliable operation of power converters. However, the state-of-the-art LC filter design of a buck dc–dc converter is limited to the specifications of voltage and current ripples and constrains in power density and cost without reliability considerations. This paper proposes a method to optimize the design of the LC filters from a reliability perspective,...
The short lifetime electrolytic capacitor brought reliability issues to the inverter system. However, state-of-the-art design of inverter DC bank concentrates on voltage ripple and stability without reliability consideration. This paper proposes a design method of paralleling film capacitors with electrolytic capacitors to construct a hybrid DC bank to prolong the lifetime of inverter. It establishes...
State-of-the-art LC filter design of buck DC-DC converter is based on the specifications of voltage and current ripples and constrains in power density and cost. Since lifetime is an important performance factor in reliability critical applications, this digest proposes a method to optimize the design of the LC filters from a reliability perspective, among other considerations. It investigates the...
