Filed: 1981-12-17
Abstract: PURPOSE:To obtain stable waveform-shaped outputs from the beginning of power supply by rapidly charging a capacitor in a smoothing circuit generating the average value potential level of a DC component in an input signal at the time of power supply. CONSTITUTION:A detecting signal from a rotating position sensor 11 is applied to an amplification part 12. The amplification part 12 amplifies differentially an output from the sensor 11 on the reference to the potential of an output terminal P2 of the sensor 11 to output a signal obtained by superposing an AC component to a DC component. The output signal from the amplification part 12 is supplied to a waveform shaping circuit 14. The circuit 14 shapes an input signal V1 by regarding a DC component obtained by smoothing the signal V1 by a time constant circuit consisting of a resistor R3 and a capacitor C1 as a threshold level and outputs a signal V2. In said circuit constitution, the capacitor C1 in the time constant circuit is rapidly charged by a charging controlling circuit 16 just after the connection of a power supply. Consequently the threshold level is raised suddenly and then stabilized, so that stable waveform-shaped outputs are obtained from the beginning of power supply.

IPC: H02P9/02
Filed: 1982-11-19
Abstract: PURPOSE:To reduce the mechanical loss by decelerating the utility minimum rotating speed of a generator in response to the energy required from a load at the low power operating time. CONSTITUTION:A generator 1 is accelerated by a drive motor 2 up to the rotating speed N1. When the rotating speed reaches N1, the generator 1 is connected to a load coil 6 through a switch 3, a rectifier transformer 4 and a rectifier 5, and stored rotary energy is supplied to a load coil 6. Then, the rotating speed of the generator is reduced to N2. The energy E generated and discharged at this time is calculated by E=K(N1<2>-N2<2>). The maximum generating and discharging energy EMAX is obtained in the range of the maximum rotating speed NH- the utility minimum rotating speed NL. In case of the low power operation, the rotating speed N12 before energizing in response to the energy E required at that time and the rotating speed N22 after energizing can be calculated in the equation shown in a drawing.
