Abstract
High-voltage converter employing IGCT switches (𝑉DC=2800V) for traction application is presented. Such a power traction driveoperates with an unstable input voltage over2000⋅⋅⋅4000V DC and with an output power up to 1200 kW. The original power circuitof the high-voltage converter is demonstrated. Development of the attractive approach to designing the low-loss snubber circuits ofthe high-frequency IGCT switches is proposed. It is established on the complex multilevel analysis of the transient phenomena andpower losses. The essential characteristics of the critical parameters under transient modes and the relation between the snubbercircuit parameters and the losses are discussed. Experimental results for the prototype demonstrate the properties of new powercircuit. The test results confirm the proposed high-voltage converter performance capability as well as verifying the suitability ofthe conception for its use in the Russian suburban train power system and other high-voltage applications
