Chapter 6: Voltage Regulator - Ajlon Tech

Voltage Regulator Outline Introduction Voltage Regulation Line Regulation Load Regulation Series Regulator Shunt Regulator Switching Regulator IC Voltage Regulator Introduction Batteries are often shown on a schematic diagram as the source of DC Voltage but usually the actual DC Voltage source is a power supply. There are many types of power supply. Most are designed to convert high Voltage AC mains electricity to a suitable low Voltage supply for electronics circuits and other devices. A more reliable method of obtaining DC power is to transform, rectify, filter and regulate an AC line Voltage . A power supply can by broken down into a series of blocks, each of which performs a particular function.

Since the Zener voltage is constant, the increase in V o ... in input voltage or load current caused by a change in load resistance, the decrease is sensed by R 1 and R 2. A feedback voltage obtained from voltage divider R 1 and R 2 is applied to …

This method charges a battery at a maximum voltage, typically from 13.8V to 15V and a maximum current depending on the charger specification. When a “flat” battery has been charged for a period of time and the maximum voltage is approached, the charge current drops off in proportion to the battery voltage increase. Constant Current Charging

Float Charge: After the constant voltage stage, the controller will reduce the battery voltage to a float voltage set point. Once the battery is fully charged, there will be no more chemical reactions and all the charge current would turn into heat or gas ...

From the current-voltage relationship for an inductor, we know that the at constant current, inductor acts like a short. Thus, the resistors R and R S have no current flowing through them, so the only current flowing is through the inductor, and i L = i S. Now we look at the situation for t > t 0. The switch has been

Sep 25, 2007 · A back current was a noticeable effect for several wave-lengths. Back current is caused by photoelectrons liber-ated from the platinum anode as a result of scattered light. Its effects become most prominent when the re-tarding voltage is high. The retarding voltage is seen as an accelerating voltage by these electrons and they travel

is that the op amp does not drive resistors and can thus maintain a high loop gain. The Basic Idea As mentioned in the pre - vious section, the volt-age across a pn junction and hence the base-emitter voltage, V BE, of a bipolar transistor exhibit a negative TC. It can be shown that, for a constant collector current, BE /, T V T Vm BE 4 VE Tg q ...

For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power. A 1E rate is the discharge ... then constant voltage charging, allowing the

A current to voltage converter is an op amp circuit which accepts an input current and gives an output voltage that is proportional to the input current. The basic current to voltage converter is shown on Figure 5. This circuit arrangement is also called the transresistance amplifier. Iin R Vout N1 Figure 5. Current to voltage converter

This tutorial examines the common ways to specify op amp gain and bandwidth. It should be noted that this discussion applies to voltage feedback (VFB) op amps—current feedback (CFB) op amps are discussed in a later tutorial (MT-034). OPEN-LOOP GAIN . Unlike the ideal op amp, a practical op amp has a finite gain. The open-loop dc gain (usually

Input offset voltage varies with temperature, and its temperature coefficient is known as TCVOS, or more commonly, drift. Offset drift is affected by offset adjustments to the op amp, but when the offset voltage of a bipolar input op amp has been minimized, the drift may be as low as 0.1 µV/°C (typical value for
