This results in higher switching losses, and the switching frequency must be reduced to prevent meltdown.

Songhe BTS7960 43A High Power Motor Driver Module/Smart Car Driver Module for Arduino Current Limit 2pc. And most likely, in a practical circuit, the real figure will be 5 or 10 times longer than that, or ~100ns. Dual DC Motor Driver Module Board, H-Bridge DC 336V 10A Peak 30A Speed Control PWM Module, MOSFET IRF3205 Quick Response Control Board for Arduino Robot Smart Car. The inductor equation is: V = L * dI/dt Therefore, under those conditions, it cannot switch faster than (50V) = (10nH) * (50A) / dt => dt = 10ns. P-channel mosfets are often used for the high mosfets in an H-bridge, but there is a cost penalty Valentine, and it is unnecessary because there are many half-bridge driver chips set up for N-channel mosfet half-bridges. (One TO-220 device has about 10nH of stray inductance. The example H-bridge uses N-channel mosfets. At low voltages (50A), the switching impedance is under 1 ohm, and layout cannot be small enough. This makes it most optimal to design, say, an inverter at 50A and 500V, and indeed, industrial inverters have quite good performance in that area.

20 kHz and full load applied to the motors, the MOSFETS did not overheat beyond their. Typical PCB layout impedances, for power switching circuits, are in the 10-50 ohm range. (3) The circuit would require four independent H-Bridge drivers. Switching is more practical, the closer the switching impedance (Zsw = Vpp / Ipk) is to the impedance of the layout (which is proportional to the impedance of free space, Zo ~= 377 ohms, and usually a few times lower because of layout). It isn't practical to design a switching circuit that switches more than 50A, through a single device, at low voltages. It isn't practical to sink more than about 50A through a TO-220 device, no matter what the datasheet might lie to you about it (tip: read the specs carefully and skeptically).
