I understand what you mean. When both mosfets are turned off, the voltage you read with a probe it's the voltage you read on a voltage divider made with high impedance components: not so meaningful. I guess that even a 1 MOhm resistor to gnd would fit.
After 1 second all 4 generators go to zero. The idea was to test 2 half waves, one period with some easy to build generators. You can use BV (behavioural generator) to create more complex waveforms, i.e. a 1 s period square wave multiplied by a 1 kHz 70% duty cycle square wave, but usually...
Hi Pik,
V3 and V4 are voltage generators emulating a square (rectangular) wave with a 70% duty cycle. It stays on at 10 V for 0.7 ms over a 1 ms period. After 500 periods ( 500 ms) V3 and V4 go to 0 V while V1 and V2 start, like V3 and V4 did before. So you have a pulsed current flowing from...
Hi Pik,
I guess you need to drive it as PWM, with a frequency much higher than 1-50 Hz. Even with 1 kHz like below, you can create a 1 Hz drive signal with a ripple of +- 500 mA @ 15 A. It would have been 50 mA @ 10 kHz.
By doing so you can use any stock mosfet as they are working in a very...
