Abstract: A circuit includes a switching module, a control module, and a driving module. The driving module is electrically coupled between the control module and the switching module for generating a driving signal. The driving module includes a normal driving unit and a fault protection unit. The normal driving unit is for turning on and off the switching module according to a first command signal from the control module. The fault protection unit is for lowering the driving signal from a driving value to a protection value according to a second command signal from the control module during a fault protection period after the control module receives a fault signal.

Abstract: The present disclosure relates to a method for controlling voltage balance of a serialized power switching device, comprising generating a reference voltage based on actual individual voltage of each switch of the serialized power switching device or setting a reference voltage based on supplied voltage to the serialized power switching device; determining an individual blocking voltage mismatch of at least one switch when existing a difference between the reference voltage and the actual individual voltage of at least one switch, wherein the individual voltage mismatch is based on the difference between the reference voltage and the actual individual voltage; calculating an individual delay mismatch for the at least one switch; and compensating the individual delay mismatch for the at least one switch. The present disclosure also relates to a system for controlling voltage balance of a serialized power switching device. The present disclosure also relates to a power switching device.

Abstract: A method used to control the operation of a converting device such that it can provide multi-level output voltage for loads. This method comprises at least the steps of: determine whether the load which the converter is providing electricity for is operating under the first condition or the second condition; generate the first pulse signal after determining that this load is operating under the first condition, select at least one of at least three different current paths, such that when the converter is selecting any of the current paths, it can provide output voltage at the same level; as well as generate the second pulse signal after determining that this load is operating under the second condition, such that the converter can perform the regular energy conversion operations.
