Voltage Droop Compensation for Marx Modulators*
نویسنده
چکیده
Marx modulators operated by solid-state switches (e.g. MOSFET, IGBT) offer an alternative to traditional high voltage (HV) modulators for rf power sources. They have the merits of compact size, high-energy efficiency, high reliability, pulse width control and cost reduction. However, Marx modulators need a complex voltage compensation circuit if they are employed in long pulse applications such as the ILC. We describe here a novel scheme to compensate the HV droop of a Marx modulator by use of inductors and fast solid-state switches. The feasibility of the scheme was analyzed and proof-ofprinciple, low-voltage experiments were performed.

Solid-State Bipolar Marx Generator with Voltage Droop Compensation
This paper addresses the voltage droop compensation associated with long pulses generated by solid-stated based high-voltage Marx topologies. In particular a novel design scheme for voltage droop compensation in solid-state based bipolar Marx generators, using low-cost circuitry design and control, is described. The compensation consists of adding one auxiliary PWM stage to the existing Marx st...

متن کاملA New Control Strategy for Voltage Restoration and Voltage Unbalance Compensation in an Islanded Droop-Controlled Microgrid
Low voltage microgrids including sensitive loads often face unbalanced load conditions. Therefore, a compensation procedure should be carried out in order to balance and restore sensitive load’s voltage. In this paper, an effective voltage control strategy has been proposed for the autonomous operation of microgrids, under unbalanced load conditions. The proposed strategy balances single-phase...

This paper presents accelerated lifetime tests on a polypropylene film capacitor. Experimental parameters (20% droop, 5 Hz repetition rate) simulate anticipated operating conditions encountered in the SLAC P2 Marx. Elevated film electric field stress is utilized as the acceleration parameter. Results indicate that, for the particular film of interest, a film stress of ~290 V/μm corresponds to a...
متن کاملVoltage Unbalance and Harmonics Compensation for Islanded Microgrid Inverters
Voltage source inverters (VSIs) are usually used for all kinds of distributed generation interfaces in a microgrid. It’s the microgrid’s superiority to power the local loads continuously when the utility fails. When in islanded mode the voltage and frequency of the microgrid are determined by the VSIs, therefore the power quality can be deteriorated under unbalanced and nonlinear loads. A volta...
