Embodiments of the application disclose a troubleshooting method and device. The method is applicable to an inverter power supply system in the power supply device. The inverter power supply system includes at least two direct current to direct current (DC/DC) power supply modules, and any DC/DC power supply module of the at least two DC/DC power supply modules includes fuses F1 and F2, relays K1 and K2, inductors L1 and L2, switch modules Q1, Q2, and Q3, and direct current bus capacitors C1 and C2. The troubleshooting method includes: if it is detected that any DC/DC power supply module of the at least two DC/DC power supply modules is a faulty module, determining a faulty component in the faulty module; and if the faulty component is a C1 or a C2, and the inverter power supply system is in a battery discharging mode, turning on a Q2 in the faulty module, so that an F1 and an F2 of the faulty module are blown, thereby disconnecting the faulty module from another DC/DC power supply module.

Electrical power is dynamically managed a power source a load. A control switching system has a plurality of monitor nodes, a control switch having two switching states, and an electrical power storage cell connected to the power source in one of the switching states for storing voltage, and operative for discharging the stored voltage to the electrical load in the other of the switching states. A programmed controller dynamically monitors operating conditions at the monitor nodes during operation of the electrical load and the power source, and switches the control switch between the switching states in response to the monitored operating conditions for supplying a voltage of a desired waveform shape to the load.

Power delivery of an image modality system for transferring power from a transmission unit (e.g., stationary unit) to a reception unit (e.g., a moving and/or rotating unit). A modulated electric signal comprising at least two modulated characteristics (e.g., such as amplitude and frequency) is configured to (e.g., concurrently) supply power to both high voltage and lower voltage components (216, 222) of the reception unit.

A method is provided for controlling an electrical system. A first characteristic value of the electrical system is determined. For the first characteristic value, a suitable first group of optimizing variables is determined. A first group of command variables suitable for the first group of optimizing variables is determined. For the first group of command variables, a first group of current boundary values is determined. For each boundary value of the first group of current boundary values, a prediction is made to obtain a first group of predicted boundary values. A probability is assigned to each predicted boundary value of the first group of predicted boundary values to obtain a first group of predicted, probability-related boundary values. All boundary values of the first group of current boundary values and of the first group of predicted, probability-related boundary values are prioritized in order to obtain prioritized boundary values. The prioritized boundary values are used to calculate at least one control value with which the system may be controlled.
