Description
Technical field
The utility model relates to high-voltage switch power supply ripple test circuit engineering field, particularly relates to a kind of high-voltage switch power supply output ripple test circuit.
Background technology
High-voltage switch power supply is common circuit in Switching Power Supply.General high-voltage switch power supply is all high voltage, and small area analysis, power is little.Even if like this, when testing high voltage power supply, still to take care.And special equipment is also needed for the test of high-voltage power supply.Loaded down with trivial details for low-tension supply during the test of such high-voltage power supply, complicated.
Wherein high-voltage power supply ripple test, generally also needs specific apparatus.Such as High Pressure Difference sub-probe.But High Pressure Difference sub-probe is on the high side, and some high-voltage probes have auxiliary source, use little convenience.So also can bring certain complicacy to test, affect testing efficiency.
Summary of the invention
For above-mentioned technical matters, the purpose of this utility model is to provide a kind of high pressure ripple test circuit.It only just can form simple high-voltage switch power supply ripple test circuit with a small amount of components and parts, and its test is simple and convenient.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of high-voltage switch power supply output ripple test circuit, include high-voltage switch power supply output voltage Vo+, output voltage Vo-, electric capacity 1, resistance 2, described high-voltage switch power supply output voltage Vo+ receives one end of electric capacity 1, the other end of electric capacity 1 receives one end of resistance 2, and the other end of resistance 2 receives output voltage Vo-.
By adopting technique scheme, the utility model has following beneficial effect:
A kind of high-voltage switch power supply output ripple test circuit, solve the problem that high-voltage switch power supply ripple test needs High Pressure Difference sub-probe, circuit devcie is few, convenient test.
Accompanying drawing explanation
Fig. 1 is this high-voltage switch power supply output ripple test circuit figure.
Embodiment
Below by further illustrating this patent by reference to the accompanying drawings.
As shown in Figure 1, a kind of high-voltage switch power supply output ripple test circuit, include high-voltage switch power supply output voltage Vo+, output voltage Vo-, electric capacity 1, resistance 2, described high-voltage switch power supply output voltage Vo+ receives one end of electric capacity 1, the other end of electric capacity 1 receives one end of resistance 2, and the other end of resistance 2 receives output voltage Vo-.
After the output of high-voltage switch power supply connects according to Fig. 1, because resistance 2 is far longer than power supply output load RL, so can be ignored it in theory to load effect.Again because electric capacity 2 is high-frequency ceramic electric capacity, according to the characteristic of electric capacity, logical interchange hinders direct current, the output ripple of such high-voltage switch power supply just almost passes through from electric capacity 1, resistance 2, the ripple at such resistance 2 two ends is exactly output ripple, and this ripple can low-tension supply method of testing routinely equally be tested.
This circuit completes high pressure switch power supply output ripple test circuit by less components and parts, and use simple, convenient test, has a wide range of applications in high-voltage power supply measuring technology.
