The discovery and application of High-frequency Currents has resulted mainly from the work of two American Scientists, Tesla and Elihu Thomson. Tesla first recognized the wonderful therapeutic possibilities of High-frequency Currents and prophesied that they would ultimately supersede the older systems based upon. • The PWM output voltage contains many high frequency harmonics (because of the fast switching) and can be a major source of EMI. • The input rectifier draws current only at the peak of the supply waveform, so the input currents have a poor form factor (i.e. the RMS value can be quite high - this does not mean the inverter is inefficient!). Accordingly, the theory of induction heating was studied so that motors and transformers could be built for maximum efficiency by minimizing heating losses. The develop- ment of high-frequency induction power supplies provided a means of using induction heating for surface hardening. Nikola Tesla - High-Frequency Currents Nikola Tesla, a scientist of great wisdom and vision, introduced a very important energy concept, high frequency oscillations, to allow our technology to be in harmony with nature and to realize new, undiscovered, limitless resources of energy.

High voltage and lower current It's not true that the current is lower at high voltage. In fact, a higher voltage will usually cause a larger current to flow, than a low voltage. High voltage overhead transmission lines might be kV but they also carry hundreds of amps. When it comes to human safety, higher voltage are almost always more. working manual of high frequency currents by noble m. eberhart, a. m., ph. d., D., M. D.

May 29,  · The high frequency current is an alternating current called the Tesla Current. It can produce a 60, to , hertz frequency, depending on how it is regulated. (The frequency indicates the repetition of the current per second).
