| Sep 11, 2013 at 10:02 | comment | added | Diego C Nascimento | @Matt Anderson I think if you are not being sarcastic you are at least not helping so much. Gate driver ICs are not a standart, and have many pros and cons, as having so much types of implementation too. For a infinity on-time of the high-side switch, a boot-strap gate drive IC, will not work (only if using a isolated supply for the high side, so no bootstrap will be used). | |

| Aug 6, 2013 at 20:40 | comment | added | Jay M | Take a look at OSMC (Open Source Motor Controller) website, that will give example circuits (at least for motor control) but you need to give more info for a more exact answer, ref previous comments. | |
| Aug 6, 2013 at 14:51 | comment | added | Matt | I'm not being sarcastic, it seems from your wording you don't know these exist. Gate Driver IC's | |
| Aug 6, 2013 at 14:35 | comment | added | Vasiliy | 1) What do you mean by low power loss? 2) When saying that you'll drive it by PWM, do you mean that you'll employ LPF to integrate the PWM, or each high phase of PWM should open the MOSFETs? | |
| Aug 6, 2013 at 14:19 | comment | added | Tut | How much current? What sort of switching speeds are you talking about? Have you considered an integrated solution (IC)? | |

spelling and consistency, title to more specifically indicate problem. Please thank by upvoting answers.

| Aug 6, 2013 at 14:06 | comment | added | Phil Frost | There are really at least three problems here, each complex enough to merit separate questions: 1) driving MOSFETs in parallel, 2) using N-channel MOSFETs for the high side, and 3) designing a proper gate driver to switch MOSFETs quickly. If the general answers already here don't address your question, I'd suggest you edit or ask a new one to be more specific. | |
