... 1. First, write the differential equation that relates the desired output to the input 2. Ignore all initial conditions (this includes switches, etc.). All initial energies (initial conditions) are assumed to have dissipated in the resistive part of the circuit. 3. Assume that the response (in this ...

... 36 kHz with a pair of 0.1 mF capacitors (in parallel effectively) for C6 and C7. It turned out that a clock timing capacitor of 1 nF for C10 sets the switching frequency to about 36 kHz which provided the optimum tuning as displayed in primary current waveform of Figure 2. The design summary of the ...

Design of High Voltage Low Power Supply Device
... The purpose of this generator is to generate a high-voltage pulse from a low-voltage DC supply. Marx generators are probably the most common way of generating high voltage impulses for testing when the voltage level required is higher than available charging supply voltages. The basic principle invo ...

... When emf induced in a conductor is stationary in a magnetic field then we call it statically induced emf. If emf is induced in a conductor due to relative motion between conductor and the field then it call it as dynamically induced emf. 3. What does speed voltage mean? It is that voltage generated ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
