Abstract: This disclosure describes techniques that address the unequal loss distribution between switches in two H bridge legs of two-level PSFB and DAB converters, where one leg reaches its temperature limit sooner than the other leg due to imbalanced losses. The techniques involve dynamically controlling the switching states of power switches in both legs simultaneously in order to maintain a consistent equivalent phase shift angle between those legs at the given operating point while enabling each leg to dynamically alternate between leading and lagging positions. The dynamic switching state transitions may be seamless, so as not to introduce any transients into the rest of the circuit. By implementing this approach, the techniques achieve a balanced loss distribution between the two legs, thereby facilitating higher power density operation.

Abstract: A voltage controller detects a voltage spike in an electrical signal received from an electrical power source. The voltage controller is implemented using a single-loop control system in a stationary reference frame. The electrical signal includes voltage harmonics caused by a non-linear or unbalanced load. The voltage controller includes a phase-compensated harmonic regulator that regulates the voltage harmonics present in the electrical signal and receives a feedback voltage of the single-loop control system. The feedback voltage is a delayed version of an instantaneous voltage of the electrical signal. The instantaneous voltage is sub-transiently stabilized into a steady-state voltage based on the feedback voltage. Sub-transiently stabilizing the instantaneous voltage is performed within a single cycle after the voltage spike is detected. The steady-state voltage has a total harmonic distortion less than a threshold total harmonic distortion and the steady-state voltage has a balanced sinusoidal waveform.

Abstract: A control system that includes a converter circuit and a control device is disclosed. The converter circuit may be configured to control a phase current of a switched reluctance machine. The control device may be configured to determine an estimated flux based on a bus voltage, a phase voltage, and a mutual voltage. The control device may be configured to determine a flux threshold based on the phase current, and determine a first limit and a second limit relative to the flux threshold. The first limit and the second limit may be scaled relative to the flux threshold based on one or more of the target speed, the load demand, or the bus voltage. The control device may be configured to compare the estimated flux with the first limit, and reset the estimated flux to the second limit based on determining that the estimated flux satisfies the first limit.
