Reduction of voltage spikes in switching half-bridge stages |
摘要 |
A path configuration for a power switch and driver can introduce independent parasitic inductance coupled to the power switch to slow a switching speed of the switch and reduce voltage spikes on the switch during switching events. The path for low side supply of the drive to the negative DC voltage reference is separate from the path of the power switch to the reference. The resulting reduction in voltage spikes due to the slowed switching time maintains performance in an audio amplifier without modifying a switch command signal to compensate for voltage spikes. The path configuration avoids reliance on specifying higher rated components that increase application costs.
