AUTOMATIC_SHUTOFF

Published:2009/6/29 22:03:00 Author:May

Prevents overcharging and dryout of battery under charge by shutting off automatically when battery reaches fullcharge voltage. Accepts wide range of batteries. Choose rectifying diodes and triacs or SCRs to handle maximum charging current desired. For initial adjustment, connect fully charged battery and adjust charge-stop pot until ammeter iust drops to zero.-Circuits, 73 Magazine, July 1977, p 34.   (View)

SOLAR_POWER_OVERCHARGE_PROTECTION

Published:2009/6/29 22:02:00 Author:May

Voltage regulator is connected across solar-cell away as shown to prevent damage to storage battery by overcharging. Series diode prevents array from discharging battery during hours of darkness. Regulator does not draw power from battery, except for very low current used for voltage sampling. Battery can be lead-calcium, gelled-electrolyte, or telephone-type wet cells, For repeater application described, two Globe Union GC12200 40-Ah gelled-electrolyte batteries were used to provide transmit current of 1.07 A and idle current of 12 mA.-T.

SOFTWARE_CONTROL

Published:2009/6/29 21:52:00 Author:May

Innovative software for Intel 8080A microprocessor eliminates need for peripheral isolation devices when using Precision Monolithics DAC-08E D/A converter and CMP-01C comparator for 8-bit A/D conversion. Technique can easily be expanded to 10-bit or 12-bit conversions and adapted to other microprocessors. Logic of microprocessor replaces conventional successive-approximation register. 8 lowest-order address bits control data bit input to DAC, using software given in article.—W. Ritmanich and W. Freeman, Software Controlled Analog to Digital Conversion Using DAC-08 and the 8080A Microprocessor, Precision Monolithics, Santa Clara, CA, 1977, AN-22 p 3.   (View)

Integrator

Published:2009/7/24 21:18:00 Author:Jessie

This circuit was originally developed to perform the mathematical operation of integration in analog computers. An integrator is essentially a low-pass filter with a frequency response that decreases at 6 dB per octave. When S1 is in position 1, C1 is discharged, which sets an initial condition of 0 V. With S1 in position 2, the amplifier is connected as an integrator, where the output changes in accordance with a constant times the time-integral of the input.   (View)

Differentiator

Published:2009/7/24 21:17:00 Author:Jessie

This circuit was originally developed to perform the mathematical operation of differentiation in analog computers. R2C2 form a 6-dB per octave rolloff network in the feedback, and R1/C1 for a similar network at the input making a differentiator a form of filter. The frequency fc refers to the relative frequency at unity gain, while fh refers to the frequency with a voltage gain of 20 dB.   (View)
