Claim 10:
11. The controller of claim 1, wherein the high-side delay circuit is configured to provide the high-side control signal to apply a delay in switching on/off the high-side switch, and the low-side delay circuit is configured to provide the low-side control signal to apply a delay in switching on/off the low-side switch, wherein during a rising phase of the half-bridge voltage:
the high-side delay circuit is configured to provide the high-side control signal to
reduce a delay in switching on the high-side switch in response to the status signal indicating the half-bridge voltage is measured as lower than a first lower limit voltage; and
add a delay in switching on the high-side switch in response to the status signal indicating the half-bridge voltage is measured as higher than a first higher limit voltage;

and the low-side delay circuit is configured to provide the low-side control signal to
add a delay in switching off the low-side switch in response to the status signal indicating the half-bridge voltage is measured as lower than the first lower limit voltage; and
reduce a delay in switching off the low-side switch in response to the status signal indicating the half-bridge voltage is measured as lower than the first higher limit voltage.
