Latest Patents

Giessler’s latest patents address power distribution and electric-drive control.

- Electrical power supply system. This invention describes a power supply system, particularly for a microgrid, with a DC bus supplied by two rectifiers. One is a diode rectifier, while the other uses switchable power semiconductors. A generator supplies both rectifiers, which can be connected at different times depending on the load.

- Parameter identification for induction machines. This method and control apparatus determine parameters for controlling an electric drive. The process applies current indicators to the machine’s three-phase winding connections and measures the d- and q-components of stator voltage and current. It uses a rotating current indicator to orient the machine, followed by a binary-noise signal while the rotor is stationary and the field winding is short-circuited. The resulting stator impedance serves as a control parameter, supporting improved drive start-up.
