Classification: CPC H  G | IPC G  H

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

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