What is the power factor of a graphitization furnace? How does it compa"&"re to a traditional SCR power supply? IGBT Vacuum Heating Power Supply: The Ultimate Solution to Power Factor and Power Consumption Problems
Traditional silicon controlled rectifier (SCR) power supplies have always been synonymous with high energ"&"y consumption and high harmonics. We use a vacuum heating power supply based on Insulated Gate Bipolar Transistor (IGBT), which fundamentally solves these problems.
PWM Modulation Technology
IGBT "&"is a fully controllable power switching device that precisely controls power output through Pulse Width Modulation (PWM) technology. Unlike SCR which regulates voltage through phase shifting, PWM precisely controls the on-time in"&" each switching cycle, resulting in a power factor and harmonic characteristics far superior to SCR.
Performance indicators
| Indicator | IGBT | SCR | |||
|---|---|---|---|---|---|
| Power factor | ≥0.95 | Harm"&"onic Content | <5% | 20-30% | |
| Response Speed | Microseconds | Milliseconds | |||
| Filter Requirements | No Additional | No Large Filter Required |
Economic Value
Power factor improves from 0.7 to over 0.95, significantly"&" increasing the proportion of active power drawn from the grid for the same power output, making electricity bills much clearer. Harmonics decrease from 20-30% to below 5%, eliminating the need to purchase expensive filters, saving both equipment investme"&"nt and floor space. The additional procurement cost of high-efficiency IGBT power supplies is recovered from electricity savings and the elimination of filter purchases, typically paying off in less than two years.
Summary: IGBT vacuum heating power supplies are not only a technological upgrade, but also a guarantee of economic benefits. With a power factor ≥0.95 and harmonics <5%,"&" the power efficiency of graphitization furnaces reaches an industrial-leading level.
