Abstract
An inverter circuit system for controlling the voltage level at the neutral point of a three-phase wye-connected load. A dc voltage source such as a pair of batteries in series and having first and second poles is connected by one pole to an inverter bus and connected by the other pole via an inductive impedance to the neutral point of a three-phase wye-connected load.
Claims11
An inverter circuit system for controlling a wye-connected load comprising;
- A wye-connected load device having a neutral point connection;
- An inverter circuit including a bus;
- And a source of dc voltage having a positive pole and a negative pole wherein a first one of the poles of the source of dc voltage is connected to the bus of the inverter circuit and the second one of the poles of the source of dc voltage is connected to the neutral point of the wye-connected load to vary the voltage level at the neutral point of the wye-connected load.
