I'm trying to figure out how to measure PWM frequency as an input. We are currently using a PIC18F66J11, and have a POL device that produces a PWM output whose duty cycle indicates the current load on the device. Our EEs have routed this PWM output back to the CCP4 pin on the PIC...
As explained above the peak value of a PWM will be mostly equal to the supply voltage fed to the circuit, while the average volatge on the meter will be the average of the ON/OFF periods of the PWMs. Switching Mosfet with PWM So if you are switching a mosfet with a PWM and find t...
(d) Using the FPGA to measure the duty cycle The FPGA has an accurate 40 MHz clock-driven counter resource. The pulse width and period of the PWM wave can be calculated by recording the counter value of the signal along the changing moment, so as to ...
Measure voltage unbalance at full load.Step 3: Measuring current unbalance Use a motor drive analyzer with a current clamp on all three drive output terminals separately to measure the current draw on each terminal.Because the current measurement will be made in a high-energy,...
To design an efficient heatsink for a surface mount PMOS FET, we should increase the drain pin board areas as much as we can. And then we can measure the Vd-s (Q1), Icharge, and Tc to calculate RΘCA. If the measured RΘCA is lower than what we expect, we should increase the...
I was just wondering if yall could help me out with how I would program the MSP430G2231 to use its ADC to measure the current that an arbitrary load is drawing from the battery that is supplying power. Can you point me to some example code or paste me ...
The object to be measured is set to the operating state inside an anechoic box, and a noise meter is used to measure the sound pressure level using a microphone. In addition, the sound-pressure-level frequency characteristics can be checked using an FFT analyzer to facilitate evaluation an...
2.1.1. Avoid Ground Return: Differential input oscilloscope should be used, because the BNC negative input in general oscilloscope is connected to the case of the oscilloscope, and the case of the oscilloscope is connected to outside line ground. If use a probe to measure the DC output, it...
• provides some scenarios of the PWM output signal response to break events coming from an internal source, an external source, or a combination of both internal and external break signals. • shows how to implement overcurrent and overvolta...
sometimes it reaches even 141vac which cause my fridge guard to chip to protect the fridge from high ⚡ I see 2 preset blue resistors inside but I am unsure as to which one to adjust to reduce the output voltage. Could you take a look at the photo and tell.me.if u figure out ...
