A Transformer-Based Front-End Circuit for Grounded Capacitive Sensors with Square-Wave ExcitationThis work proposes and experimentally characterizes a novel front-end circuit for capacitive sensors with one electrode grounded, which are quite common in liquid-level and position measurement applications. ...
so that the power devices force the transformer winding to also oscillate in the SPWM mode and ultimately generate an optimized pure sine wave at the secondary side. The magnetic induction of the pulsed SPWM across the transformer winding finally gets the shape of a pure sine wave due to...
Because of the phenomenon described by its transfer function, a sum of responses appear when the square wave frequency increases, which causes a resonance response with high voltage, in several cases, greater than common turn ratio of the transformer. With parallel capacitances inserted on output,...

1. A square wave generator for the supply of power to at least one unit which is selectively connectable to a busline, said generator having a source of current which through an inductance applies a pulsating direct current to a center tap of a primary winding of a transformer through one ...
converter consists of three transistors, two diodes and the primary winding of a transformer which serves as an inductive load. An input square wave is fed to the base of the first transistor (3) which is also connected to a first side of the primary via a first diode (12). The first...
The output of solid state square-wave generator 6 is connected through conductors 7 to the primary winding of a transformer 8, located directly at the weld electrodes 10 and 12. The electrodes normally are the single turn secondary winding or form a part thereof, this secondary turn being ...
