Abstract
A multilayer printed circuit board dV/dT filter with powder core toroids includes an input terminal connecting powder core toroids and output terminals connecting the second end of powder core toroids. Damping resistors and shunt capacitors and resistors are connected using multilayer routing on printed circuit boards. The powder core toroid inductors reduce voltage spikes by increasing PWM switching times.
