Abstract
An apparatus includes a first DC bus, a second DC bus, a first converter circuit coupled to the first DC bus, and a second converter circuit coupled to the second DC bus. The apparatus further includes a limiter circuit coupled to the second DC bus, a first control circuit configured to sense a voltage on the first DC bus and to responsively control the first converter circuit to limit the voltage on the first DC bus, and a second control circuit configured to sense a voltage on the second DC bus and to responsively control the limiter circuit to limit the voltage on the second DC bus. The apparatus may include a modulation conversion circuit configured to provide a set of switch control signals to the converter circuits and implemented in a module that is also used to implement the second control circuit.
