摘要： A three-point converter with NPC diodes disposed between bridge halves and a center tap of an intermediate circuit is proposed. A decoupling network is provided for the upper bridge half, a first input of which decoupling network is connected to a positive pole of the intermediate circuit and a first output of the decoupling network is connected to a positive pole of the three-point converter. Furthermore, provision is made of a further decoupling network for the lower bridge half, a first input of the further decoupling network is connected to a negative pole of the intermediate circuit and a first output of the further decoupling network is connected to a negative pole of the three-point converter. The remaining inputs of both of the decoupling networks are connected to the center tap of the intermediate circuit. The remaining outputs of both of the decoupling networks are connected via the NPC diodes to the upper and lower bridge halves. A commutation voltage for the main switches of the upper and lower bridge halves is decoupled from a halved intermediate circuit voltage (Vdc/2) independently of one another by the decoupling networks.

The method also includes comparing each of the induced voltages with a predetermined threshold voltage, measuring time differences between the time instants at which the induced voltages crosses the threshold voltage, and modifying one or more of the control signals on the basis of the measured time differences in the respective following state change for balancing the switching transient behavior.

摘要： A current stiff power conversion system, such as a rectifier, inverter, or AC-to-AC converter is provided wherein power converter switching devices in the power conversion system may be switched at or near zero voltage conditions to minimize or eliminate switching losses and increase switching frequencies. Zero voltage switching conditions are achieved by providing a snubber capacitor across each switching device in the power conversion system, and connecting an active commutation unit, including an inductor and an active commutation unit switching device connected in series across DC bus lines in parallel with the bridge of power conversion switching devices. Zero voltage switching conditions for the power conversion switching devices are achieved by controlling the power conversion switching devices and the active commutation unit to establish a resonance between the snubber capacitors and the active commutation unit to drive the voltage across incoming switching devices in the power conversion system to at or near zero. Zero current switching of the active commutation unit switching device, and reduced switching device stress in the power conversion system, is achieved by controlling the power conversion switching devices to establish zero current switching conditions and a desired snubber driving voltage for the active commutation unit before the active commutation unit is turned on to establish the resonance condition. Since zero voltage switching conditions for the power conversion switching devices is achieved each switching cycle, the power conversion system may be controlled using a PWM control scheme.

摘要： An open-loop and closed-loop control method is proposed for a single-phase or polyphase three-point converter which is connected to a DC voltage intermediate circuit, having two series-connected main switches/inverse diodes between each DC voltage connection and each load connection. The common junction point of the two inner main switches forms the load connection. An active clamped switch with an inverse diode is connected between each common junction point of an inner main switch and an outer main switch and the center tap of the DC voltage intermediate circuit. As a result of which, two possible paths are formed for connecting a load connection to the center tap. Irrespective of the direction of the load current, at least one of the two active clamped switches (T5, T6) is connected to the center tap together with at least one inner main switch for connection of a load connection. The provides a circuit that can carry the current deliberately through the upper path, the lower path, or through both paths, to the center tap during a null state.
