Title: Power supply
Inventor: BANBA SHIGEKI
IPC: H02M3/155
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To protect a smoothing circuit surely against damage through simple circuitry even upon occurrence of such a situation as an MOSFET is substantial ly turned on. SOLUTION: A power factor improving circuit 5 switches an MOSFET 7 to bring the current waveform of an AC power supply close to the voltage waveform thereof. When an MOSFET 7 is substantially turned on, the DC voltage Vi increases. But since Zener diodes 41, 42 sustain the DC voltage Vi at a level lower than the withstanding voltage of a smoothing capacitor 9, the smoothing capacitor 9 is not damaged. Furthermore, a fuse 43 is blown out when the Zener diodes 41, 42 are short-circuited to protect each circuit element of a power supply. Since only the Zener diodes 41, 42 an the fuse 43 are required, they cause no burden on the cost or the mounting on a board.

Filed: 1988-06-11
Abstract: PURPOSE:To secure the aimed control independently of the activity state of an oxygen concentration sensor by calculating the engine control factor value under the engine conditions except an oxygen concentration sensor, when the degree of activity of the oxygen concentration sensor is inactive. CONSTITUTION:In a control circuit 20, the degree of activity of an oxygen concentration sensor 26 is judged from the sensor impedance in an output processing circuit 42. When the oxygen concentration sensor 26 is in inactive state, the engine control factor value such as fuel injection quantity is calculated from the engine conditions without using the output value of the oxygen concentration sensor 26. While, if it is judged that the oxygen concentration sensor 26 is active, the engine control factor value is a calculated from the output value of the oxygen concentration sensor 26. Therefore, the fuel injection quantity in the inactive state of the oxygen concentration sensor 26 is set close to an ideal value, while after an active state is generated, the ideal engine control is carried out by the output of the oxygen concentration sensor 26.
