Title: Energization control circuit
Inventor: MORIOKA TATSU
IPC: H02P7/29
Filed: 1983-05-31
Abstract: PURPOSE:To reduce a leakage current by connecting a control transistor to the base of a main switch transistor and connecting a PUT to the base of a control transistor. CONSTITUTION:Switches S1, S2 are normally in nonconductive state, and since a programmable unijunction transistor PUT is in nonconductive state, a control transistor Q2 and hence a main switch transistor Q1 is in nonconductive state. When the switch S1 becomes conductive, a gate current is flowed to the PUT, the PUT is conducted, the transistor Q2 and hence the transistor Q1 becomes conductive to flow a drive current to motor M. When the switch S2 is made on with the switch S1 being conducted, the PUT becomes nonconductive, and the transistor Q2 and the transistor Q1 become nonconductive, thereby stopping the supply of the current to the motor M.
