The Modulator System C. The Corner Cutter D. Filament Power Supply In order to achieve the design objectives of this contract, our design approach has to follow state-of-the-art technology in solid-state design. The evolution of third generation IGBT technology and the various power supply topologies makes it a challenge to make the right choice for our present application. The design objective calls for generating narrow pulses of various pulse-widths under single pulsing conditions. The cathode pulses will drive a CPI Magnetron operating in the C-Band frequency with minimum peak output power 1.0 Mw. The power supply section is self-contained in an enclosure as shown in Figure 1.0. Our design is based on series resonance topology driving a full bridge circuit. The modulator is a hard-tube type, utilizing IGBT technology, and is under oil environment. The mechanical enclosure for the modulator is shown on Figure 2.0 System Specifications The specifications for the systems are outlined in the Appendix along with the magnetron specifications. General Technical Discussion As previously mentioned, the whole system consists of the high-voltage power supply and the solid-state hard tube modulator. The solid-state power supply contains the following sections: A. Off-Line Rectifiers, Filters, and Controls B. Series Resonance Full Bridge Inverter C. Series Resonance Frequency Modulation Control D. High Voltage Output Section E. Low Voltage Power Supplies F. Hard Tube Modulator Control G. Solid-State Filament Power Supply The Modulator section contains the following sections: A. Switch Driver Assy B. PRF Driver C. High Power Switch Section D. Magnetron Peak Current Detector The input voltage for the system is 220 VAC single phase and it enters the system via a connector located in the rear lower panel of the cabinet. The input line voltage enters the system via a circuit breaker located on the control panel. The control panel is located on the front upper section of the main cabinet. Figure 3.0 shows the mechanical configuration of the system. The front view of cabinet shows the control panel located on the upper section. The main electrical system diagram is shown on figure 4.0. The main power is switched on by the circuit breaker on the control panel and is further fused before entering the power supply section. It enters the front end of the power supply and is applied to the power factor correction section. The Power Factor Correction Module performs the rectification, in-rush current limiting and preregulation of the input line voltage. The power factor module provides a preregulated DC Voltage level of 360 VDC. The above 360 VDC is applied to the input of the series resonance converter which, in turn, provides a final adjustable level of 0-900 VDC available at the modulator section. The above DC output is sent to the modulator section through three of wires leaving the back of the power supply section. The input PRF, which is TTL level, enters the control panel and is further processed by the Modulator control circuit. It enters the Modulator Control Circuit, which transforms this input signal to a selectable pulse-width level proper for triggering the modul…
