摘要： The present disclosure relates to a power supply circuit and an electrical device. The power supply circuit includes: a first switch (S1); a first capacitor (C1) connected in series with the first switch (S1); a voltage sampling device (16) configured to detect a voltage of the first capacitor (C1) and/or a power supply bus to which the power supply circuit is connected; and a control circuit (18) configured to output a control signal based on the detected voltage, wherein the first switch (S1) is configured to be switched on or off based on the control signal. In this way, a low-voltage withstanding capacitor with a large capacitance can be achieved in the power supply circuit by switching out the capacitor when the power supply bus voltage is high and switching in the capacitor to assist in power supply when the power supply bus voltage is low. The power supply further includes at least oone second switch (S2), the at least one second switch (S2) configured to be selectively switched on to charge from the power supply bus to the first capacitr (C1) or discharge from the first capacitor (C1) to the power supply bus.

摘要： A robot controller having a power supply circuit supplying power to a motor of a robot, includes a capacitor, a discharge resistor discharging electric charge stored in the capacitor, a first switch element passing and interrupting a current flowing in the discharge resistor, a first voltage detection unit detecting a voltage at a primary side of the power supply circuit, and a first control unit controlling on and off of the first switch element based on a detection result of the first voltage detection unit. Further, the first control unit sets the first switch element to be continuous to pass a current in the discharge resistor when the voltage detected by the first voltage detection unit is equal to or lower than a first threshold.

摘要： Eine Hochspannungskaskade weist mehrere Kaskadenhalbstufen (3) auf, die jeweilige Stufeneingänge (4), jeweilige Stufenausgänge (5) und zwischen den jeweiligen Stufeneingängen (4) und den jeweiligen Stufenausgängen (5) eine jeweilige Kondensatorschaltung (6) und eine jeweilige Diodenschaltung (7) aufweisen. Die Stufeneingänge (4) der ersten Kaskadenhalbstufe (3) sind mit Eingangsanschlüssen (1) verbunden, über die der Hochspannungskaskade eine Eingangsspannung (Ue) zugeführt wird. Einer der Stufenausgänge (5) der letzten Kaskadenhalbstufe (3) ist mit einem von mehreren Ausgangsanschlüssen (2) verbunden, über die eine Ausgangsspannung (Ua) abgegeben wird. Im Übrigen sind die Stufenausgänge (5) einer jeweiligen Kaskadenhalbstufe (3) mit den Stufeneingängen (4) der jeweils nächsten Kaskadenhalbstufe (3) verbunden. Die Diodenschaltungen (7) sind auf ersten Zusatzplatinen (9) der Hochspannungskaskade angeordnet, die mit einer Hauptplatine (8) der Hochspannungskaskade elektrisch und mechanisch verbunden sind. Die ersten Zusatzplatinen (9) sind orthogonal zur Hauptplatine (8) orientiert und folgen entsprechend der elektrischen Abfolge der Kaskadenhalbstufen (3) in einer Erstreckungsrichtung (x) gesehen sequenziell aufeinander. Die ersten Zusatzplatinen (9) sind im Wesentlichen orthogonal zur Erstreckungsrichtung (x) orientiert. Die Kondensatorschaltungen (6) der Kaskadenhalbstufen (3) sind seitlich neben den ersten Zusatzplatinen (9) auf der Hauptplatine (8) angeordnet, und zwar entsprechend der elektrischen Abfolge der Kaskadenhalbstufen (3) und alternierend auf der einen und der anderen Seite der ersten Zusatzplatinen (9).

摘要： A system can include a bi-directional converter circuit (101) comprising a plurality of switches and at least one flying capacitor. One or more the plurality of switches can experience overvoltage in a fault state. The system can include a control module (103) operatively connected to the plurality of switches to control a state of the plurality of switches. The control module (103) can be configured to receive a sense signal indicative of flying capacitor voltage and to control the one or more switches of the plurality of switches to turn on or remain on to prevent switch overvoltage of the one or more switches if the flying capacitor voltage is outside of a normal range.

摘要： A method for intermittently discharging an inverter (5) in an energy storage apparatus (100) and an energy storage apparatus (100) using the method are disclosed. The method includes a protection step; and an intermittent discharge step, which includes having a battery management system (2) detect a charge level of a capacitor (51) and send it to a control unit (1), and when the charge level is below an activation threshold, having the control unit (1) control a battery pack (3) to perform a first discharge procedure to charge the capacitor (51) for at least two times intermittently until the charge level reaches the activation threshold, thereby providing fast charge for the capacitor (51).
