IPC: H02J7/34
Filed: 1994-07-11
Abstract: PURPOSE:To make it possible to generate signals both to a positive side PWM control circuit and to a negative side PWM control circuit using a single current transformer, by making its primary winding out of a resistance material having a low temperature coefficient, and using it as a current detecting resistance. CONSTITUTION:A current transformer 10 uses for its primary winding 11 a metal resistance material having a low temperature coefficient, such as manganin (Mn: 12%, Ni: 2-3%, Fe 1%, Cu: remainder) and constantan (Cu: 55%, Ni: 44%). The primary winding 11 uses d.c. resistance originating from its length and cross-sectional area as current detecting resistance. Like conventional current transformers, a secondary winding 12 is formed with a specified turn ratio to the primary winding 11 and insulation provided. This makes it possible to use a single current transformer to detect current passing through the common lines in a switching power circuit having both positive output and negative output. As a result, it is possible to reduce the number of parts and the price of the product, and to improve the reliability of circuits.

IPC: H01H47/22
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To utilize the electromagnetic energy stored in a coil for the next electromagnetic action of the coil by generating a high DC voltage by regenerating the energy. SOLUTION: When a control voltage 5 is impressed, a switching element Q1 is conducted and a current flows to a coil L. Simultaneously, another switching element Q2 is also conducted. When the charged voltage of a capacitor C is higher than the applied voltage of a DC power source 4, a current flows through the switching element Q2 and a voltage is applied across the coil L. When the charged voltage of the capacitor C is equal to the voltage of the power source 4, the current flowing from the capacitor C to the coil L is stopped and another current is directly supplied from the power source 4 to the coil L. When the application of the control voltage 5 is stopped while the current flows to the coil L, the switching elements Q1 and Q2 are cut-off.  When the elements Q1 and Q2 are cut off, the induced inverse electromotive force of the coil L is stored in the capacitor C through a diode D2. The voltage of the capacitor C is applied across the coil L when the switching elements Q1 and Q2 are turned on next.
