Abstract: According to one aspect of the present disclosure, there is provided a power converter apparatus that includes at least two paralleled switching bridges connected to a Direct Current (DC) bus with each bridge generating a pulse-width-modulated (PWM) voltage output to non-isolated load, and an isolation transformer which primary winding is connected across the outputs of the paralleled switching bridges and which secondary winding connected to an isolated load. In one mode of operation, the parallel bridges are synchronized in phase and generate the same PWM voltage waveforms across the transformer, thus power is mainly delivered to non-isolated load. In the other mode, the parallel bridges are not generating the same PWM voltage waveforms, thus power is mainly delivered to the isolated load through the transformer.

In one embodiment, a method includes adjusting a threshold direct current (DC) bus voltage for a dynamic brake in a wind turbine power converter above a reference DC bus voltage based on at least one system condition. The method further includes gating the dynamic brake on when an experienced DC bus voltage is equal to or greater than the threshold DC bus voltage, and inputting a dynamic brake condition into a controller when the dynamic brake is gated on. The method further includes determining if a grid fault has occurred, reducing power generation of the wind turbine if no grid fault has occurred, and blocking the power converter if a grid fault has occurred. The method further includes gating the dynamic brake off when the experienced DC bus voltage is less than the threshold DC bus voltage.
