Title: Power supply equipment
Inventor: YAMAZAKI SHIGEAKI
IPC: H02M7/537
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To reduce cost and size by eliminating a diode which was provided to cause regenerated current to flow. SOLUTION: A first switching element SW1 is connected between the base and the emitter of a transistor Q1, and a second switching element SW2 is connected between the base and the emitter of a transistor Q2. These switching elements SW1 and SW2 are on/off-controlled by a control section 2. Due to this structure, regenerated current IF1 (or IF2) caused to flow in one of two secondary windings n2 (or n3) of a current transformer CT1 induces a current in the other secondary winding n3 (or n2), which prevents the transistor Q2 (or Q1) from coming turning into on state. As a result, simultaneous turn on of the serially connected two transistors Q1 and Q2 can prevented, and moreover no diode is required to cause the regenerated currents IF1, IF2 to flow, for reducing cost and size of power supply equipment.

Title: Instantaneous value control system of load current
Inventor: KUROKI KAZUO
IPC: H02M3/135
Filed: 1983-09-29
Abstract: PURPOSE:To facilitate a noise countermeasure by narrowing the ON or OFF period of a reference pulse in response to the instantaneous value of a load current, thereby maintaining a switching frequency constant. CONSTITUTION:When a load current reaches the upper limit value during the ON period of a transistor 2 with the output pulse of a phase regulator 11 varying at the ratio of ON/OFF in response to the current command value as a reference, the ON period is narrowed, next ON signal is outputted when the output of the regulator 11 becomes high level, the OFF period is narrowed when the load current reaches the lower limit value during the OFF period of the transistor 2, and the next OFF signal is outputted when the output of the regulator 11 becomes low level. Thus, the ON/OFF frequency of the transistor 2 becomes the same as the output frequency of the regulator 11, the noise generated when the transistor 2 operates ON or OFF becomes constant, thereby facilitating a noise countermeasure.
