Abstract
A gate driver circuit comprises a gate-driver assembly, a transformer, first and second circuit voltage outputs, first and second switching devices, and a controller. The gate-driver assembly comprises a first and second voltage inputs and a first and second voltage outputs coupled to a primary winding of the transformer. The first and second switching devices are coupled to the secondary winding and respectively coupled to the first and second circuit voltage outputs. The controller is configured to cause the first circuit voltage output to supply a positive output voltage by supplying a higher first input voltage to the first voltage input than to the second voltage input and is also configured to cause the first circuit voltage output to supply a negative output voltage by supplying a higher second input voltage to the second voltage input than to the first voltage input.
