摘要： A DC to AC inverter has a DC power input port, a buck converter, a buck/boost converter, an output filter and an AC output port. The DC power input port has a positive input terminal and a negative input terminal, both connected to a DC source. The AC output port is connected to a single-phase utility system. When the single-phase utility system is in positive half cycle, the buck converter generates a positive half-cycle signal of sinusoidal current. When the single-phase utility system is in negative half cycle, the buck/boost converter generates a negative half-cycle signal of sinusoidal current. In either the positive or negative half cycles, only one power electronic switch is switched in high frequency to reduce switching loss. Further, the negative input terminal of the DC power input port of the invention can be connected to a neutral line of the single-phase utility system.

摘要： A three-phase three-wire active power filter includes a dc power capacitor, a power converter, a filter inductor set, a reactive power compensating capacitor set, a combined capacitor/resistor filtering set and a control circuit. The dc power capacitor provides with a regulated voltage. The power converter includes a two-arm bridge power converter, and has a pair of ac terminals and a pair of dc terminals. A phase of the three-phase three-wire active power filter, without control of the power electronic switch set, directly connects with any one of the dc terminals. Consequently, the number of power electronic switches employed in the two-arm bridge power converter of the three-phase three-wire active power filter can be reduced.

摘要： An active harmonic suppression equipment is consisted of a dc capacitor, a power converter, a serially connected inductor/capacitor set, a C-R-C filter set and a control circuit. The dc capacitor operates as an energy storage device and supplies a dc voltage, and the power converter electrically connected thereto is used to convert the dc voltage into a compensating voltage. The inductor/capacitor set and the C-R-C filter set are commonly converting the compensating voltage into a compensating current injecting into a power feeder in order to suppress harmonic currents generated by nonlinear loads, thereby adjusting an utility current to be approximated as a sine-wave.
