Title: Dc-dc converter
Inventor: NISHIDA MICHIFUMI
IPC: H02M3/155
Filed: 1990-11-26
Abstract: PURPOSE:To make possible to lower withstand voltage of a P-channel FET and the gate-source withstand voltage by subjecting a first output signal from a pulse processing circuit to level shift through a circuit comprising a diode and a capacitor and then employing thus level shifted signal as a gate signal of the P-channel FET. CONSTITUTION:An interval B prevails under steady state and when a first output pulse from a pulse processing circuit 9 goes 0(v), gate potential drops by VP1 to provide reverse bias and thereby the current flowing through a diode 11 is negligible. Consequently, a capacitor 10 is charged and the gate voltage rises to a final level VIN while the source-gate voltage of a P-FET 2 lowers. Upon entering into an interval C, the first output pulse from the pulse processing circuit goes H again and the gate potential rises again by VP1 to bias the diode 11 forward and thereby the gate voltage of the P-FET 2 drops quickly to the final level VIN. Operations for the intervals B and C are then repeated.

Filed: 1988-12-22
Abstract: PURPOSE:To secure detection capacity with high accuracy by constituting the second voltage setting resistor positioned on an earth side out of the first and second voltage setting resistors of a positive characteristic temperature-sensitive resistance element having positive characteristics to a temperature change. CONSTITUTION:A fixed resistor 31 is the first voltage setting resistor and a positive characteristic thermistor 32 is the second voltage setting resistor and the intermediate point 33 between the resistor 31 and the thermistor 32 is connected to the control terminal 9 of a three-terminal variable output type stabilized power supply circuit 6. A control resistor 34 is connected to the thermistor 32 in parallel and selects a resistance value to control the gradient of the DC constant voltage, which is outputted to magnetic resistance elements 1, 2 from the circuit 6, to a temp. rise. In this constitution, when circumferential temp. rises, the resistance value of the thermistor 32 rises and, therefore, the control voltage of the circuit 6 rises. The DC constant voltage applied to the elements 1, 2 from the circuit 6 rises and the temp. fluctuation components of the detected voltages outputted from the elements 1, 2 are compensated. Therefore, output voltage containing no temp. fluctuation component is obtained from the detection signal output terminal 5 of the elements 1, 2 and the detection capacity of a magnetic sensor can be enhanced.
