    Abstract: In described examples, an integrated circuit includes first and second transistors, a switch, a capacitor, a resistor, and first and second comparators. A first terminal of the switch is coupled to a first terminal of the resistor. A second terminal of the switch is coupled to a second terminal of the resistor, a first terminal of the capacitor, and a gate of the first transistor. The first comparator is configured to receive at the first input a first reference voltage, and an output of the first comparator is coupled to a gate of the second transistor. The second comparator is configured to receive at the first input a second reference voltage. A second input of the second comparator is coupled to a second input of the first comparator. An output of the second comparator is coupled to a control input of the switch.

    Abstract: The present disclosure pertains to the field of power electronics technologies, and provides a grid-connected control method and system for a grid-forming converter without a grid-side voltage sensor. The grid-connected control method includes: performing coordinate transformation on a phase of a three-phase capacitor voltage sampled by a phase-locked loop (PLL) to obtain a first phase; in response to control of a first pulse width modulation (PWM) pulse signal, introducing a reference phase, and performing negative feedback regulation on a difference between the reference phase and the first phase to obtain a second phase; and in response to control of a second PWM pulse signal, performing a modulo operation on a difference between the reference phase and the second phase to obtain a third phase, where the third phase is used to replace a phase of the PLL to perform coordinate transformation of a system.

    Abstract: A controller for a power converter includes a generator module configured to generate a sequence of pulses each having a width defined by a rise moment, R, and fall moment, F, stored in respective RM and FM registers. The sequence of pulses have a repetition rate, T, that is modulated by a repetition period, RP, value stored in a RP register. A memory of the controller has tables of R values, F values and RP values configured to be written into the generator module RM, FM and TM registers respectively. A direct memory access (DMA) module of the controller is configured to write R, F and RP values from the respective memory table into the RM, FM, and TM registers respectively, in response to a DMA trigger. A core coupled to the DMA module is configured to write the R, F and RP values into the memory table.
