According to certain aspects, an electric-propulsion thruster is used as part of a base or platform which also includes a power converter, having a plurality of inductors and other electrical components, and a printed circuit board (PCB). The PCB includes a layer at which the other electrical components and printed circuit inductor traces, for the plurality of inductors, are secured. The electric-propulsion thruster includes a housing (e.g., as part of the base or platform) providing a cavity and having at least one structurally-rigid side wall along the cavity, where the PCB is integrated with the electric-propulsion thruster for a compact arrangement which can be used to propel the apparatus. Such a compact design might be used as an important part of thruster spacecraft architecture such as micro-satellites (e.g., CubeSats).

Improved control of electrical power consumption is provided with 'Smart Dim Fuses' (SDF) which can alter their output voltage as provided to the load circuits they are connected to. SDF units can replace conventional circuit breakers in electrical panels. The voltage control capability provided by SDF units can lead to improved control of electrical power consumption, since many loads can smoothly operate at lower power consumption when the voltage they are driven with decreases. SDF units can comply with relevant safety requirements, such as uninterrupted neutral connections between electrical mains and load circuits. SDF units can also provide a current limiting function that can substitute for the protective action of conventional circuit breakers.

Precision fabrication of 3D objects is used for fabricating passive electrical components. A 3D scaffold is fabricated and then electrically conductive and/or insulating layers are deposited on the scaffold to form the electrical component.

A resonant DC-DC converter for generating high voltage MHz bi-polar DC pulses includes a left multi-level resonant rectifier bank [] connected to a positive electrode [] and coupled via capacitive isolation to a left RF amplifier terminal []; a right multi-level resonant rectifier bank [] connected to a negative electrode [] and coupled via capacitive isolation to a right RF amplifier terminal []. Each multi-level resonant rectifier bank comprises multiple resonant rectifier stages [-], where each stage comprises two capacitors for capacitively isolating the stage, an output capacitor, a MOSFET switch connected to an adjacent MOSFET switch of an adjacent stage, and a gating resonant circuit connected to the MOSFET switch, whereby MOSFET switches in the banks can be passively controlled by RF signals from a left RF amplifier and a right RF amplifier.

Resonant power converters that replace the conventional impedance matching stage with series or parallel connections between resonant inverters and resonant rectifiers are provided. Two or more resonant rectifiers can be connected in series or in parallel to the resonant inverter to provide impedance matching. Similarly, two or more resonant inverters can be connected in series or in parallel to the resonant rectifier to provide impedance matching. Electrical isolation of DC voltage between input and output is provided using only capacitors.
