To connect a main supply with a load and backup battery, the simplest link is to use the diode-OR connection. However, it will not work when the battery voltage is greater than main supply voltage. The circuit below is used to overcome that problem. Component list : 9V Battery Main switch-mode supply voltage ranges from [...]
Three phase AC motor speed controller is a three phase sine wave power inverter with variable frequency. Since the motor is synchronized with the line frequency, to control the speed of three phase AC motor can be done by controlling the frequency of the power line supply. Even thought three phase power inverter is a [...]
The LMH6553SDEVAL evaluation board is designed to aid in the characterization of National Semiconductor’s LMH6553 fully differential amplifier with output limiting clamp in an 8-pin LLP package. The LMH6553 is part of the LMH high speed amplifier family. The evaluation board can be used as a guide for high frequency layout and as a tool [...]
