A half bridge is driven to provide by pulse width modulation a desired output. The switching elements include drivers which have power supplies. The condition of the power supply is predicted by use of a model of operating parameters. This model is used in conjunction with a signal applied to one of the switch drivers to determine whether an operating criterion for the power supply of the other switch driver is met. If the condition is satisfied then a signal to the other switch driver is enabled. |
