Converter circuit for (dis)charge of capacitive and/or piezoelectric adjuster for motor vehicle IC engine fuel injection system, comprises bridge circuit coupled to small buffer capacitor, larger storage capacitor and transformer

摘要

The converter circuit (1) for (dis)charge of capacitive adjuster (6) is set between two supply terminals (2,3) of energy source. Between terminals is incorporated charge capacitor (7), chargeable by energy source to preset voltage. There is first series connection (9,11) of transformer primary (9) and bridge circuit (11) in parallel to charge capacitor. To primary is inductively coupled secondary (16), which is fitted between output terminal (17) of bridge circuit and output (4) of converter circuit, forming second series connection with capacitive, e.g. piezoelectric adjustor. INDEPENDENT CLAIM is included for car engine with fuel injection and invented converter circuit.
