摘要： A power converter which does not require any separate power source for a switching regulator, etc., and has a small circuit scale and from which electric power based on the positive electrode-side bus of a DC power source can be obtained inexpensively. When the switching element (T1) of an upper arm is turned on, the potential at a point (U) becomes nearly equal to that at a point (P), and a current (ic1) flows in a capacitor (C1) form the positive electrode side of an insulated power source (21) through a diode (D7) so as to drive the switching element (T1) and the capacitor (C1) is charged. The electric power (Vc) of the capacitor (C1) is used as the electric power based on the positive electrode-side bus (P) of the DC power source.

摘要： The power converter has one section to rectify an AC input using PWM control with a number of switch sections, another section to invert the DC into an AC output again using PWM control with a number of switch sections, a common section working with the first section for rectification and with the second section for inversion, plus PWM control sections for the first and second sections. Each of the sections comprises at least a pair of switch sections of the upper and lower arms. One AC input terminal is directly connected to one AC output terminal to make a common phase available. The common phase has a connecting point with the upper arm switch section and the lower arm switch section.

摘要： A power converter which can provide a power supply grounded on a positive electrode bus of a DC power supply without adding an additional power supply such as a switching regulator and reduce a circuit size and cost is described. When a switching device T1 of an upper arm is ON, the potential at point U is nearly equal to the potential at point P, and the current ic1 flows from the positive electrode of a first drive power supply 21 into a capacitor C1 via a diode D7 to charge the capacitor C1. A power supply Vc formed by the capacitor C1 can be used as a power supply grounded on a positive electrode bus P of the DC power supply.
