PS-SPS Thyratron Power Trigger Consolidation About me Enrique de Nicolas Lumbreras 25 years, Spanish Industrial Engineering 5 years degree: Bachelor degree in General Engineering (Materials, Electrical, Mechanical, Energy…) Master degree in Electronics and Automation One and a half years experience working on Power Electronics Research One paper presented in Congress (SAAEI 2016) Small experience in Industry: 3 months working as a Control Engineer Spanish Trainee (FTEC) in TE-ABT under the supervision of Mr. Etienne Carlier 18/10/2016 PS-SPS Thyratron Power Trigger Consolidation

PS-SPS Thyratron Power Trigger Consolidation Introduction: What is a Thyratron? Switch with the same operating as the thyristor (SCR) Based on gas ionization technology Suitable for high power applications with short switching times Thyristor Thyratron 18/10/2016 PS-SPS Thyratron Power Trigger Consolidation

PS-SPS Thyratron Power Trigger Consolidation Project: Pulse Forming Network Thyratron Kicker magnets Trigger Amplifier The objective of this project consist in: Analysis of the different types of Thyratron triggering systems actually in operation Design, development and prototyping of a new system compatible with all the different existing configurations 18/10/2016 PS-SPS Thyratron Power Trigger Consolidation

Systems actually in operation Power Mos HV trigger amplifier Implemented in the PS complex 3.5kV pulse 1600V Mos/IGBT Thyratron Trigger G2 Implemented in the SPS complex 1.6kV pulse 400V IGBT Thyratron Trigger G1 Implemented in the SPS complex 400V pulse 18/10/2016 PS-SPS Thyratron Power Trigger Consolidation

Power Mos HV trigger amplifier LV HV DC/DC Buck converter Resonant Power Supply Transformer 10:110 Mosfet Trigger 1 Line AC DC Mosfet Trigger 2 Control Mosfet Trigger 3 Based on the HV capacitor discharge technique It`s needed to trigger all the modules to recharge the capacitors 3.5kV pulse 18/10/2016 PS-SPS Thyratron Power Trigger Consolidation

1600V Mos/IGBT Thyratron Trigger Switch Voltage Divider Protection DC HV Power Supply Simplier system Extra Power supply is needed Switches block the HV all the time Less Triggering frequency due to the bigger capacitor charging time 18/10/2016 PS-SPS Thyratron Power Trigger Consolidation

400V IGBT Thyratron Trigger Switch Voltage Divider Protection DC HV Power Supply Simplier system Extra Power supply is needed Mosfets block the HV all the Time Less Triggering frequency due to the bigger capacitor charging time 18/10/2016 PS-SPS Thyratron Power Trigger Consolidation

PS-SPS Thyratron Power Trigger Consolidation Systems comparison Power Mos HV Trigger Amplifier Advantages: More frequency due to the smaller capacitor (input) charging time. Less stress on the Switches, Mosfets doesn’t block the voltage all the time. No extra Power Supply is needed. 1600 V Mos/IGBT Thyratron Trigger and 400V IGBT Thyratron Trigger Advantages: Simpler system. It`s not needed to trigger all the modules to recharge the capacitors.
