how can I tell Matlab to solve an equation symbolically without giving values to the variables? For example: 2x + 5 + 6x will become 7x + 5.
Thanx in advance!
How does the error-amp of a switch mode power suply work? I know a lot about it already, but:
- I don't know at which frequencies to place the poles and zeros;
- how much should the phase shift be?
- how to choose the component values?
thanx again
I saw many circuits on the internet with totempole drivers for FETs. Now I built such a totempole in a SMPS, but it doesn't work correctly. Now someone told me that a levelshifter should ALWAYS be used, even with totempole. The reason: when the mosfet is ON, the gate-drain voltage will both be...
