Abstract

PURPOSE: To obtain the potential at neutral point with a simple constitution, by connecting the two Zener diodes in series between the base and ground of the control transistor, and obtaining netural potential from the junction of the Zener diodes.
CONSTITUTION: The Zener diodes ZD2, and ZD3; are connected in series between the base and ground of the control transistor Tr2. ZD2, and ZD3; are connected at the junction of the electrolytic capacitors C2, and C3 and also to the netural potential supply terminal 6. This circuit does not require the provision of breeder resistor and is less in power consumption and stable neutral point potential can be obtained.
