Multilayer Ceramic Capacitors Crisis Management in Automotive Industry

The evolution of HEV/EV technology has completely changed the scenario of automotive industry with a set of new challenges and benchmarks in power electronics arena. These requirements brings new challenges to designers in terms of achieving high power density (compact) and highly immune to electromagnetic radiations (EMI/EMC). Automotive market is moving towards digitalisation and autonomous cars. IOT, AI and digital electronics plays a vital role in making autonomous car real. In near future the automotive industry completely ruled by autonomous vehicles. As technology grows the requirements of power electronic circuits are also in proposition. Each component in the power electronic circuits has its own importance. Such one of the component in these circuit boards is capacitor. At present most of the automotive suppliers are using the Multi-layer ceramic capacitor as one of the prominent and most depend components in the schematics. Currently electric & electronic industry suffering with shortage in these capacitors. These requirements made the authors to look for an alternative approach(s) in the design. To look into these issues the author(s) of the manuscript suggests two alternative approaches along with a technical assessment in purview of automotive industry. Recommended approaches could be a potential solution for designer(s) and not to compromise with design requirements. Such one of the capacitor, which could be an alternative to MLCC is Polyethylene Naphthalate (PEN) Film Capacitor. In the present manuscript, characteristics of MLCC are compared with Polyethylene Naphthalate (PEN) Film Capacitor with an automotive grade.
