Switch control system

A method for generating a switched output signal including more than two discrete voltage levels, the method comprising;

• controlling at least two switches in a switch group using a sequencer, including:
• controlling respective on and off states of the at least two switches to generate the switched output signal;
• controlling the at least two switches to proceed through a specified sequence of switch states, wherein each switch state includes a respective state for each of the at least two switches;
• and
• controlling the switch group to enter switch states including:
• at least two power states, configured for generating a portion of the switched output signal;
• and
• at least one transition state, configured for preventing at least one of shoot-through, reverse current, or damage to the switch group when switching between power states.

A switch control system for controlling a switch group, including at least six switches, to generate a switched output signal, including at least five discrete voltage levels, the switch control system comprising:

• a sequencer, configured to control respective on states and off states of the at least six switches to generate the switched output signal, including to:
• control the at least six switches through a specified sequence of switch states, wherein each switch state includes a respective state for each of the at least six switches;
• and
• a controller, configured to:
• send configuration information to the sequencer;
• wherein:
• the sequencer is configured to control the respective on states and off states of the at least six switches using PWM signals based on the received configuration information
• wherein the switch states include:
• at least two power states, configured for generating a portion of the switched output signal;
• and
• at least one transition state, configured for preventing at least one of shoot-through, a reverse current condition, or damage to the switch group when switching between power states.
