Abstract
A switching arrangement for a high voltage load provides high voltage pulses to the load. The switching arrangement includes switching modules, where n is typically (75). A load capacitance is Cd is required to avoid voltage overshoot at the load and is provided by a capacitance of nCd arranged in parallel with each switch.
Claims8
A high voltage switching arrangement for applying a pulse across a load which includes a capacitive component, said high voltage switching arrangement comprising:
- a first capacitor for providing electrical energy to the load;
- and
- a switch stack for connecting the first capacitor to the load, the switch stack comprising a plurality of switch modules arranged in series with the first capacitor and a plurality of load capacitances in parallel across the switch modules, the load capacitances together providing the required additional capacitance across the load to compensate for voltage overshoot.
A high voltage switching arrangement for applying a pulse across a magnetron which includes a capacitive component, said high voltage switching arrangement comprising:
- a first capacitor for providing electrical energy to the magnetron;
- and
- a switch stack for connecting the first capacitor to the magnetron in a series arrangement, the switch stack comprising a plurality of switch modules arranged in series and a plurality of second capacitors arranged in parallel across the switch modules where the second capacitors distribute capacitance of the magnetron across each switch module so that capacitance applied at the magnetron exceeds any stray capacitance generated at the switch stack.
