Voltage stabilization power supply performance index test circuit

Published:2011/6/22 2:12:00 Author:TaoXi | Keyword: Voltage stabilization, power supply, performance, index, test circuit

The voltage stabilization power supply has two kinds of technology index: the first one is the characteristic index, it includes the input voltage, the output voltage, the output current and the output voltage adjustment range.etc; the other one is the quality index which can be used to measure the stability of the output DC voltage, it includes the voltage regulation coefficient (or the voltage adjustment rate), the output resistance (or the current adjustment rate), the ripple voltage (ripple coefficient) and the temperature coefficient. The test circuit is as shown in the figure. (View)

The filter circuit of the output return circuit

Published:2011/6/22 2:35:00 Author:TaoXi | Keyword: filter circuit, output return circuit

The filter circuit of the output return circuit
In the frequency range of 0.15～1MHz, the harassment mainly exists in the form of common mode, in the frequency range of 1～10MHz, the harassment mainly exists in the forms of differential mode and common mode, when the frequency range is higher than 10MHz, the harassment mainly exists in the form of common mode. The differential mode harassment is caused by the switch tube that is in the operating state, when the switch tube opens, the current of the power line rises linearly, when the switch tube closes, the current is zero, so the current of the power line is the high frequency triangle pulse current, and it has rich high-frequency harmonic component.

Single peak feature filter circuit

Published:2011/6/22 2:34:00 Author:TaoXi | Keyword: Single peak, feature, filter circuit

The single peak feature filter circuit which is composed of the single op-amp is as shown in the figure. This circuit uses a op-amp and a few components to form the filter, it has the same features with the filter circuit that is composed of the LC components, if you do not change the circuit gain, you can adjust the resonant frequency easily. This circuit uses the potentiometer PR1 to adjust the resonance frequency. When the value of PR1 is from the maximum to the minimun, the resonance frequency adjustment range is: (View)
