Claim 18:
19. The power control system of claim 14, wherein the controller is configured to transition from the bypass mode to one of the discharge-boost mode and the charge-buck mode by:
starting in an initial state with the first power switch, the second power switch, the third power switch, and the fourth power switch off based on first, second, third, and fourth pulse width modulated signals and the first and second bypass switches on; and
sequentially transitioning the first power switch on, the first bypass switch off, the third power switch switching on and off at a duty cycle greater than zero and less than one based on the third pulse-width modulated signal, the second bypass switch off, and the fourth power switch switching on and off at a duty cycle greater than zero and less than one based on the fourth pulse-width modulated signal.
