Title: Power control circuit for lowering generation of electromagnetic noise
Inventor: SUZUKI ATSUHIKO
IPC: H04B15/00
Filed: 1988-04-20
Abstract: PURPOSE:To lower the generation of an electromagnetic noise by constituting the title circuit so that an intermediate voltage of voltages of both ends of a load becomes constant. CONSTITUTION:Signals having a PWM waveform which have been generated by a logic circuit A are inputted to bases of an NPN type transistor Q1 and a PNP type transistor Q2, respectively by allowing one of them to pass through an inverter B. The transistors Q1, Q2 constitute an emitter follower circuit, a response waveform of an output against an input waveform is quick enough, and the transistors Q1, Q2 become ON or OFF roughly simultaneously. Resistances R3, R4 use an equal resistance so that when the transistors Q1, Q2 are both OFF, an intermediate voltage of voltages of both ends of a motor M becomes 1/2 of a pull-up voltage Vcc. In such a way, a pulse voltage applied to electric wires D1, D2 which have been connected to both ends of a load is negated and it does not occur that an electromagnetic noise is generated in the periphery.
