| Zusammenfassung | For all high voltage applications power supplies with appropriate performance are required. These applications might be subject to research for partial discharges, charging circuits for circuit breaker testing or calibration of high voltage measurement equipment. Since often different demands are asked for, adequate supplies cannot be found on the market. In the case of DC power supplies these requirements might be the ripple, the stability of the output voltage as well as the setup of the entire voltage source. If all these challenges are demanded on a very high level the only solution is a custom-made supply. In the case of the PTB high voltage power supply demands the ripple of less than 1·10-5 and a stability of also 1·10-5 over a period of 5 hours can be provided by only two manufacturers worldwide. Therefore, we will present a method to generate a high frequency alternating current at high voltages, which is the key for small residual ripples. An analogue control establishes the stability together with the corresponding feedback divider. By the means of a Greinacher voltage multiplier this allows the generation of an extremely stable and pure DC voltage to generate any desired output voltage. Different approaches will be presented for voltage ranges from 1 kV to up to 1000 kV. Different primary inverter topologies are discussed along with their benefits and drawbacks. The heart of the entire circuit is the high voltage transformer that operates at frequencies higher than 10 kHz. Consequently, a major focus will be set on the design of this transformer and the insulation considerations. Also, the voltage multiplier circuit for these operating conditions will be discussed. In the end different measurement techniques are presented to evaluate the performance according to the critical requirements for high precision calibration levels and synthetic high-power circuit breaker testing. |
