Half-bridge inverter modules with advanced protection through high-side to low-side control block communication

A communication system for use in a switching module, comprising:

• a low-side control block coupled to control switching of a low-side switch of the switching module, wherein the low-side control block is further coupled to be referenced with a low-side reference system ground;
• and
• a high-side control block coupled to control switching of a high-side switch of the switching module, wherein the high-side control block is further coupled to be referenced with a floating node of the switching module, wherein during steady state operation, the low-side control block is coupled to send signals during each switching cycle to the high-side control block to turn the high-side switch on and off, wherein an encoded status update is communicated from the high-side control block to the low-side control block through a first single-wire communication link coupled between the high-side control block and the low-side control block, wherein the encoded status update is a current pulse coupled to be received by the low-side control block through the first single-wire communication link from the high-side control block.
