The impedance is a key parameter for evaluating a component/circuit. The automatic balancing bridge method can be used to measure the impedance. The MICROTEST Impedance Analyzer ensures a high-precision impedance measurement within a wide bandwidth of 10Hz-50MHz.

Use the Impedance Analyzer to measure the current flowing through the component and the voltage at both ends of the component to obtain the Z and θ values. Then, calculate the L, C, R, and other parameters based on the Z/θ value. To lower the error, choosing the proper equivalent circuit mode is very important.

Taking the measuring of capacitors as an example, choose the series equivalent circuit mode to measure the high capacitance or low impedance (below 100Ω), and choose the parallel equivalent circuit mode to measure the small capacitance or high impedance (above 10kΩ).

The number of passive components on the common BOM is five or more times the number of ICs. As the operating frequency of the power supply increases continuously, the second-level parameter characteristics of these passive components become very important (series resonance frequency SRF, parallel resonance frequency, parasitic capacitance, parasitic inductance, etc.).

For electrolytic capacitors, plastic capacitors, box capacitors, tantalum capacitors, ceramic capacitors, laminating capacitors, etc., the inductance and the resistance on the lead will affect the characteristics at a different frequency band.

Under the trend of continuously increasing the operating frequency of the switching power supply technology, in recent years, continuous innovations have been made in power ferrite materials to achieve a higher magnetic permeability under the circumstance of higher frequency and larger magnetic flux density.

The magnetic component is one of the key components of power converters in power electronics. Once the magnetic saturation occurs, the switching power supply will become overheated or even burn up in a serious situation.

MICROTEST offers a set of test equipment to conduct a full analysis of the magnetic saturation and permeability characteristics of magnetic components, and perform a full verification of magnetic saturation current and temperature rise current of magnetic components.
