How to choose TVS diodes to dispel flyback surges from relay …

Tīmeklisvoltage is greater than the voltage driving the inductive load. The DC blocking voltage can be found in the datasheet of a diode supplier. The forward current should be equal or greater than the maximum induced current flowing from the inductor. A nominal voltage of around 0.6 - .7V is required for them to operate. Disadvantages of using a … Tīmeklis2024. gada 9. jūn. · A flyback power supply involves using a transformer to store energy from the primary winding and relay the stored energy to the secondary winding. This is a unique development of the application of transformers in power supply design, as they are usually used for stepping up or down the voltage. Fig. 1 shows an inductor connected to a battery - a constant voltage source. The resistor represents the small residual resistance of the inductor's wire windings. When the switch is closed, the voltage from the battery is applied to the inductor, causing current from the battery's positive terminal to flow down through the inductor and resistor. The increase in current causes a back EMF (… proverbs a time for everything
