Step 2: Assign a Test Point Manually The general rule of test points on a printed circuit board is that each net needs to have a probeable point to test. These “test points” need to be known and cataloged in the Printed Circuit Board design system for reports to be generated that th...
Modems and routers all have a switched-mode power supply (SMPS) that is plugged into an outlet. The EMI created by this SMPS can travel along your electrical wiring and Ethernet cables. You can test this with an AM radio and electric field meter (pictured below). Newer “Gigabit” modems...

B1 is an “arbitrary behavioral voltage source.” Its “value” field is a formula rather than a constant; in this case the formula is the shifted baseband signal multiplied by the carrier waveform. In this way B1 can be used to perform amplitude modulation. ...
First determine the maximum peak safe operating voltage of the electronic circuit which needs the protection and then apply an MOV specified to conduct near about this voltage limit. For example, suppose it's anSMPS devicewith a max capability of 285V RMS from the mains input, implies that th...
Consider a simple example of a control system configuring motors using analog sensors. Here, we have connected the central control unit (microcontroller) to a motor through driver circuits. We have powered the PCB using a switch-mode power supply (SMPS), a power management unit, and a battery...
There are many more important parameters for the SMPS design, however for the purpose of this introduction we will focus only on those mentioned in the first and last point from the list above. Note that Altium provides cursors in the Spice simulation module to determine signal values or freque...
UM2837 User manual STNRG012: How to set Non-Volatile Memory (NVM) parameters Introduction This user manual provides information for developing applications with the STNRG012 digital combo multi-mode PFC and time shift LLC resonant controller. The STNRG012 is an STMicroelectronics...
Gate Driver Circuits: Used to drive power transistors and IGBTs isolated from control electronics. Switch Mode Power Supplies: Small planar transformers used in DC-DC converters, LLC resonant converters, and other SMPS. CM Chokes: Provide common mode noise filtering while passing differential signals...
Modern SMPS devices have efficiencies that exceed 90%. However, switching converters deliver noisy outputs due to the rapid switching of current across their inductor, producing a current that resembles a triangular waveform. The voltage of an inductor is proportional to the differential current of ...
