Two switches based AC-link phase-shifter

[摘要] References(5)This work proposes a PWM quadrature phase shifter which uses only two driven switches. The PWM control is based on DC signals asynchronous from the grid, free of PLL and trigonometric calculations, the control can be accomplished with a low-cost micro controller.
