Claim Text:
1. A gate control circuit for controlling gates of at least a half side of an H-bridge circuit, the gate control circuit comprising: an input terminal configured to connect to a PWM signal; a power terminal configured to connect to a voltage source that supplies a positive voltage; a ground terminal configured to connect to a ground reference; and a control circuit connected with the input terminal, the power terminal, and the ground terminal, the control circuit comprising: one of the high side switches and one of the low side switches are respectively connected with the input terminal and configured to be controlled by the PWM signal; and the high side switches are respectively open when high inputs are fed to gates thereof and closed when low inputs are fed to gates thereof, while the low side switches are respectively open when low inputs are fed to gates thereof and closed when high inputs are fed to gates thereof.
