With the increasing market for electrified vehicles (EVs), the demand for onboard chargers (OBCs) is growing fast. OBCs open up the possibility to charge the car at fast-charging DC stations and with AC sources in a reasonable time. Such systems are currently going up to 22 kW with operating voltages up to 800 V.

Silicon-based capacitors are typically single MIM (metal-insulator-metal) or multiple MIM structure electrostatic capacitors built by semiconductor technologies. Silicon dielectrics are either silicon dioxide (MIS) or silicon nitride (MOS) insulating layers; however, semiconductor manufacturing techniques such as atomic layer deposition (ALD) can be used to form other dielectric materials on top of the silicon substrate. High-density silicon-based capacitors use 3D nano-structured electrodes to achieve higher surface area and, thus, higher capacitance value.

Tantalum and Niobium capacitors belong to electrolytic capacitor types, and they are known for their high capacitance in small dimensions (high energy and power density), reliability and stability of its parameters. Traditionally, tantalums’ advantages over aluminum electrolytic capacitors have been found in terms of capacitance per volume, parameter stability over temperature, and longevity; tantalums

The basic idea of electrolytic capacitor types is to maximize the surface area of electrodes and thus increase their capacitance value and capacitance density. Fine pores and cavities created on the electrode (anode) surface are then covered by a dielectric – usually insulator/semiconducting metal oxides. The electrolyte in a liquid/wet, gel or solid form is used as a medium to contact the high surface from the second side and bring it by its electrical conductivity mechanisms to the second electrode (cathode).

The chemically reactive nature of the materials used in aluminum capacitors is problematic on two points: the dielectric layer’s stability and the device’s long-term mechanical integrity. Since the aluminum oxide dielectric layer in these devices is formed through an electrochemical process, it can also be eroded by an electrochemical process simply by reversing the applied voltage. This is why most aluminum capacitors are polarized; the application of voltage with the wrong polarity causes rapid erosion & thinning of the dielectric, resulting in high leakage current and excessive internal heating.

Inductors, also referred to as coils or sometimes choke, are important passive components along with resistors (R) and capacitors (C). Coils usually refer to wound conductive wires, and among them, those with a single wound wire have in recent years particularly been referred to as inductors.
