Dear Readers,
I got this PS2501 optocoupler datasheet at here. In the image shown, the rise time and fall time is microseconds and I am afraid it's not suited for my needs as it will produce some switching losses in H-bridge circuit running at 100kHz minimum.
Are there any very-high speed optocoupler suited running at 300kHz with very little switching loss in the modern marker nowadays?
And, regarding the graph of switching time vs load resistance, it worries me because when RL is large, the switching time will increase a lot and it would mean that if i attach a mosfet as RL as a switch (Resistance of GS very high), the switching time will be extremely large which makes my H-bridge suffer from switching losses ?
Thank you for reading
