PROBLEM TO BE SOLVED: To provide a power supply equipment and method for voltage resonance which can solve a problem of a narrow output control width which has been a disadvantage of a voltage resonance type power supply and which can reduce a switching loss, at the time of control to a minimum. SOLUTION: A voltage resonance type converter consists of a switching element 201 connected to a power supply, a first resonance capacitor 204 serially connected to the switching element 201, a main switching element 202 serially connected to the first resonance capacitor 204, an exciting coil 203 connected to a connection between the first resonance capacitor 204 and the main switching element 202 and the power supply, a second resonance capacitor 205 connected in parallel to the main switching element 202, and regenerative diodes 206, 207 connected in parallel to the switching element 201 and the main switching element 202 respectively. |
