This abstract first appeared for US patent application 20240421694 titled 'DRIVING CIRCUIT, DRIVING SYSTEM AND POWER CONVERSION DEVICE
Original Abstract Submitted
a driving circuit comprises: a driving voltage generation unit configured to, in a driving circuit that can drive a first semiconductor switching element (ql) including a first terminal, a second terminal, and a control terminal, supply a driving voltage (vgl) to the control terminal to switch between on and off of the first semiconductor switching element; a comparator configured to compare a voltage (vql) between the first terminal and the second terminal with a threshold voltage (vth1); and a driving signal generation unit that generates a driving signal (gsl′) to be input to the driving voltage generation unit on the basis of an output from the comparator and a first control signal (gsl) that is generated by a control device and controls switching of the first semiconductor switching element.
