摘要： In a power converter including a plurality of switches, a plurality of freewheeling diodes each electrically connected in anti-parallel with a respective one of the switches, a freewheeling current input electrically connected to an output terminal of each of the switches, and a freewheeling current output electrically connected to an input terminal of each of the switches, a plurality of freewheeling current paths are defined, each of which is an electrical path passing through a respective one of the freewheeling diodes from the freewheeling current input to the freewheeling current output. At least one of the freewheeling current paths is a maximum path having a maximum impedance among the freewheeling current paths. A voltage drop across the freewheeling diode included in the maximum path is less than a voltage drop across each of the other freewheeling diodes when a freewheeling current flows through each of the plurality of freewheeling diodes.

摘要： An objective of the invention to provide a hybrid converter station for HVDC system and the method operating the same. The hybrid rectifier station for high voltage direct current system includes: at least one AC bus; at least one line commutated converter configured to convert a portion of AC power supplied from the at least one AC bus to DC power transmitted on HVDC transmission line of the high voltage direct current system thereby generating reactive power demand; and at least one voltage source converter; wherein: the at least one line commutated converter and the at least one voltage source converter are coupled in parallel to the HVDC transmission line; and the at least one voltage source converter is configured to compensate the reactive power demand via the parallel coupling while converting another portion of the AC power supplied from the at least one AC bus to DC power transmitted on the HVDC transmission line. By reusing the VSC supplying both of the active power for power transmission and reactive power for LCC reactive power compensation, it is helpful for raising the total active AC power rating of the HVDC transmission system without incorporating extra power conversion device or changing the design of LCC. Besides, the nominal DC voltage of LCC and VSC is the same and the power flow shifting process is not needed.

摘要： A DC link capacitor in a drive system for an electric vehicle is quickly discharged using only local action within an inverter module and without any extra components to dissipate the charge. The inverter has a phase leg comprising an upper switching device and a lower switching device coupled across the capacitor. A gate driver is coupled to the phase leg to alternately switch the switching devices to ON state according to a PWM signal during pulse-width modulation of the drive system. The gate driver is configured to discharge the link capacitor during a discharge event by simultaneously activating the upper and lower switching devices to transitional states. Thus use of transitional states ensures that the switching devices provide an impedance that dissipates the capacitor charge while protecting the devices from excessive temperature.

摘要： We describe a photovoltaic (PV) panel system comprising a PV panel with multiple sub-strings of connected solar cells in combination with a power conditioning unit (microinverter). The power conditioning unit comprises a set of input power converters, one connected to each sub-string, and a common output power conversion stage, to provide power to an ac mains power supply output. Integration of the micro-inverter into the solar PV module in this way provides many advantages, including greater efficiency and reliability. Additionally, embodiments of the invention avoid the need for bypass diodes, a component with a high failure rate in PV panels, providing lower power loss and higher reliability.
