  • Leakage Current Testing Requirements for Medical Grade

    First, testing for leakage current through reliable methods allows for more accurate specifications of transformers and the products in which they’re used. Transformers that have been tested poorly can easily be mis-specified; for example, using incorrect or incorrectly calibrated testing equipment could show leakage current of a transformer at 100 µA, when in reality it is closer to 300, 400, or even 500

    The leakage inductance of the HF transformer enhances the ZVS range of the dc–ac converter but reduces the duty ratio of the converter, which increases the conduction loss. Thus, the leakage inductance of each transformer is designed to achieve the highest efficiency, as illustrated in Fig. 5.18. For the sinusoidally modulated dc–ac converter, the ZVS capability is lost twice in every line cycle.

  • Leakage Current Testing Requirements for Medical Grade

    Modern standards for leakage current require that the transformer be properly energized before measuring leakage current. Since today’s insulating materials are extremely good, most leakage current is due to the capacitive currents that are created from the difference in voltage across the insulating barrier. For example, 120V line voltage
