WebInstantaneous VDSON and current through the device are required for the RDSON calculation. Fig. 2 presents the VDSON current sensor configuration on the three-phase inverter [27]. http://www.chinesechip.com/chip/405708f0e162468db82bc7699e5efb2a.html
WebCombined use of DCR and RdsON current sensing assures precision in voltage positioning (by reading droop current across inductors DCR) and safe current sharing and OCP per each phase (by reading the current across LS RdsON). Droop function can be anyway disabled to perform precise and load-insensitive regulation.
