Description

The Eight-Pulse Gate Multiplexer block routes gate voltage signals to the eight switching devices in a Bidirectional DC-DC Converter block. The block multiplexes the eight separate gate signals into a single vector.

When you set the Gate-control port parameter to Electrical, the block exposes conserving ports that represent electrical reference points. These ports are associated with the individual phase voltages that connect to the high-side switching devices and the negative DC voltage common to each low-side switching device in the Bidirectional DC-DC Converter block.

Examples

Dual Active Bridge Control

Control the output voltage of a dual active bridge DC-DC converter. Each switch is on for 50% of its switching period. A phase shift controller introduces a variable phase shift in the output bridge and controls the output voltage. The input voltage and the system load are held constant throughout the simulation. The total simulation time (t) is 0.25 s. At t = 0.15 s, the voltage reference changes.
